First, the study analyzes the factors that impede the attainment of optimal power transfer efficiency (PTE) in a mirror-symmetric RWPT system composed of a pair of conventional HFLs under practical feeding conditions. Subsequently, the field distribution conditions requisite for achieving optimal PTE in the HFL-based RWPT system are derived. Guided by these conditions, a mirror-symmetric RWPT system comprising a pair of improved HFLs is designed to achieve optimal PTE under practical feeding conditions. The improved HFL consists of a redesigned HFL and a transition layer. The transition layer not only mitigates the impedance mismatch at the interface but also achieves a time-reversal symmetric field distribution required for optimal PTE. The redesigned HFL undergoes axial compression and refractive index distribution modification, thereby reducing the lens’s refractive index while maintaining its profile height. Finally, to validate the effectiveness of the proposed design, a midrange RWPT prototype based on the improved HFL is designed and fabricated. The experimental results show that the RWPT system based on the improved HFL can achieve a PTE of 41% at a transfer distance of <inline-formula> <tex-math>$d=8lambda $ </tex-math></inline-formula> when fed by a horn antenna, demonstrating a 70% PTE improvement compared to the RWPT system based on the conventional HFL.","PeriodicalId":13102,"journal":{"name":"IEEE Transactions on Antennas and Propagation","volume":"73 6","pages":"4075-4085"},"PeriodicalIF":4.6,"publicationDate":"2025-02-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144219794","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The proposed FTA has been designed by using phase-controlled 3-bit unit-cells (UCs) based subwavelength metasurface (MS) structure. To achieve the wideband response of the UCs, the generalized scattering matrix (GSM) method is used. Also, a low-profile differential V-shaped microstrip patch antenna (DVMPA) is designed as the FTA feed to achieve low cross-polar levels, and symmetrical pattern throughout the frequency range. Furthermore, the metaheuristic optimization algorithm incorporating particle swarm optimization (PSO) technique is used for the phase distribution of the transmitarray (TA) aperture for realizing wideband flat response with low sidelobe level (SLL) and constant aperture efficiency (AE) throughout the frequency band. The peak gain of the FTA antenna is 22.7 dBi with an AE of 42.5% by maintaining a reduced profile height-to-diameter ratio (<italic>H</i>/<italic>D</i>) of 0.13. Further, the 1 and 3-dB gain bandwidths (GBWs) are found to be 4.23 and 8.17 GHz, respectively, viz., 28.2% and 54.5% along with suppression of SLLs by over 18 dB throughout the band of operation; thereby offering significant performance improvement compared to its closest competitors. The proposed FTA antenna can be used in Ku-band radio astronomy, space communication, synthetic aperture radar (SAR), and other allied fields requiring high-directive antennas.","PeriodicalId":13102,"journal":{"name":"IEEE Transactions on Antennas and Propagation","volume":"73 5","pages":"3316-3321"},"PeriodicalIF":4.6,"publicationDate":"2025-02-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143918738","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To maintain an accurate estimate of complex permittivity changes during the ablation process, we integrate the time-of-difference-of-arrival-based ablation boundary prior into the contrast source inversion (CSI)-based nonlinear inverse scattering framework. This incorporation mitigates the ill-posed problem of the original CSI scheme by restricting the region of interest (ROI) using the time-difference-of-arrival (TDOA) prior. Specifically, by focusing on the characteristics of the CSI cost function, our approach simultaneously determines an appropriate ablation boundary and the temporal decrease of complex permittivity, which is closely correlated with the temperature change of the ablated tissue. The effectiveness of our proposed scheme is validated using the 2-D finite-difference time-domain method with realistic breast phantoms, demonstrating accurate dielectric profile reconstruction.","PeriodicalId":13102,"journal":{"name":"IEEE Transactions on Antennas and Propagation","volume":"73 6","pages":"3986-3999"},"PeriodicalIF":4.6,"publicationDate":"2025-02-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144219628","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Accurate estimation of channel parameters including delay and complex amplitude is essential for positioning applications. However, multipath propagation of wireless signal significantly impacts the performance of channel estimation, particularly the estimation accuracy degrades in closely spaced multipath environment. In this communication, we propose a whale optimization algorithm (WOA)-based channel estimator to extract channel parameter in closely spaced multipath environment. We derive the fitness function based on the maximum likelihood criterion. Both the simulation and measurement-based validation for closely spaced multipath environment reveal that the proposed method outperforms several state-of-the-art methods including as space-alternating generalized expectation–maximization (SAGE), gray wolf optimizer (GWO), and salp swarm algorithm (SSA). The results conclusively demonstrate that the WOA is well-suited for dense multipath parameter estimation.","PeriodicalId":13102,"journal":{"name":"IEEE Transactions on Antennas and Propagation","volume":"73 4","pages":"2684-2689"},"PeriodicalIF":4.6,"publicationDate":"2025-02-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143800926","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, wideband imaging radar can obtain the complex structural features of targets through the high-resolution range profile (HRRP), thus identifying simple scattering point deception jamming. In this article, a method of target HRRP deception imitation is proposed based on TCDM. The nonperiodic time modulation model of TCDM is derived, and it is theoretically proved that the complex distribution of scattering points in HRRP can be accurately imitated by a single TCDM with a specific nonperiodic sequence. Comparisons with existing schemes reveal that the proposed solution combines the advantages of flexibility, realism, operability, and resource efficiency. Both simulation and experiment results show that the cosine similarity between real and imitated HRRP peaks can exceed 90% in various scenarios, which verifies the robustness and practicality of the proposed method.","PeriodicalId":13102,"journal":{"name":"IEEE Transactions on Antennas and Propagation","volume":"73 6","pages":"4061-4074"},"PeriodicalIF":4.6,"publicationDate":"2025-02-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144219626","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this work, we demonstrate that incorporating the gap-waveguide (GW) technology into the radiator section can be leveraged to improve bandwidth and directivity of antenna arrays, mimicking a dual perfect electric conductor–perfect magnetic conductor (PMC) Fabry–Perot (FP) resonant cavity.

Experimental results demonstrate that, within the frequency region of 318.0–375.6 GHz, the metasurface can achieve the conversion from LP waves to cross-polarized waves without external biasing. However, when a saturated biasing voltage of 8 V is applied, the y-LP waves can be converted to right-handed CP (RHCP) reflection waves. Similar phenomenon is observed for x-LP incidence, as the x-LP waves were converted to left-handed CP (LHCP) wave in reflection.

To address this gap, we propose a theoretical framework aimed at emphasizing the maximum number of independent MIMO channels that an antenna can provide in a cell and compare it with the physical upper bounds, and the latter is provided by the degrees of freedom (DoFs) of the field in the same cell. This approach allows for the definition of novel figures of merit for the quantification of antenna array performance, and the individuation of design strategies targeting the maximization of the number of independent channels, the average efficiency, and the maximum average gain within a specific cell. By exploring the DoF of the electromagnetic (EM) field, we establish the physical upper bounds for system performance. To this end, this article details the embedded element patterns (EEPs), their related efficiency correlation matrix (ECM) and cell correlation matrix (CCM), and orthogonal field modes, discussing the practical implications of these concepts for MIMO systems. The findings underscore the significance of sophisticated antenna models in enhancing network capacity, efficiency, and reliability.
