However, THz wireless transmission has drawbacks, including spreading loss and absorption loss, resulting from its high-frequency characteristics, which considerably restrict the transmission distance. It is essential to use antenna diversity methods, such as multiple-input multiple-output (MIMO) technology, to combat these impacts. Meanwhile, an orthogonal frequency division multiplexing (OFDM) scheme is employed to resist dispersion effects in fiber optic links and multipath fading in wireless links. Discrete Fourier transform-spread (DFT-s) technology reduces the PAPR of OFDM signal and alleviates high-frequency power attenuation.

The leakage of LO signal caused by the residual optical carrier of the carrier-suppressed modulation severely impacts the communication quality of the microwave photonic multichannel upconversion system. In the proposed mixer, the LO signal and the intermediate frequency (IF) signal are individually modulated in the form of carrier-suppressed single sideband (CS-SSB) with orthogonal polarization. By aligning the polarization direction of the two CS-SSB signals with the polarizer, their residual optical carriers cancel with each other, thereby facilitating the high LO isolation. Furthermore, the polarization control can introduce a tunable phase difference between the two polarized beams, enabling phase tunability of upconverted signal after photodetection. Owing to the CS-SSB modulation form, the LO and IF sidebands can be amplified efficiently in the optical domain, which results in the linearity enhancement of upconversion. A proof-of-concept experiment is carried out with results showing that a carrier-to-sideband ratio (CSR) of −45.1 dB and an upconversion isolation of 50.4 dB are realized. The spurious-free dynamic range (SFDR) of subchannel is enhanced by 15.1 dB. A three-channel upconversion of the IF signals with the same frequency without interchannel crosstalk and the capability of phase shifting for subchannel are demonstrated.","PeriodicalId":13272,"journal":{"name":"IEEE Transactions on Microwave Theory and Techniques","volume":"73 7","pages":"4218-4226"},"PeriodicalIF":4.1,"publicationDate":"2024-12-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144550556","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The frequency-dependent permittivity of a material is extracted from the measured reflection coefficient through a coaxial probe. Current models that relate the reflection coefficient to the dielectric properties of the material struggle to balance accuracy and computational efficiency, limiting their utility in near real-time applications. This article introduces a novel matrix-based closed-form solution of the reflection coefficient of an open-ended coaxial probe. The approach combines full-wave analysis with a Taylor series expansion, leading to a straightforward matrix calculation. By reformulating the forward problem to decouple the material properties from the geometric properties of the probe, the required numerical integral only needs to be calculated once for each probe geometry. This significantly reduces computational time while providing similar or greater accuracy than existing methods. The model has been validated experimentally using two coaxial probes and four reference liquids, achieving an average error of 3.15%. Further validation through 9600 simulations in Ansys HFSS demonstrated an average error of 2.9%. When applied to inverse problems for estimating material permittivity, the model exhibited an average error of 4.35% while being 376 times faster than existing state-of-the-art models, with similar or enhanced accuracy. These advancements facilitate real-time, full-wave permittivity spectroscopy, offering substantial benefits for medical diagnostics and monitoring.","PeriodicalId":13272,"journal":{"name":"IEEE Transactions on Microwave Theory and Techniques","volume":"73 7","pages":"3919-3929"},"PeriodicalIF":4.1,"publicationDate":"2024-12-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144550737","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The receiver utilizes an orthomode transducer (OMT) to achieve polarization diversity, effectively doubling channel capacity and enhancing spectral efficiency without adding circuit complexity or increasing the number of components compared to traditional single-polarization designs. In addition, the receiver integrates a differential rectifier, fabricated using 65-nm bulk CMOS technology, to enable wireless power transfer. This integration allows the system to support both wireless communication and energy harvesting simultaneously. A mathematical model is developed to guide the receiver’s design. To validate the concept, a prototype receiver is fabricated and tested. The receiver successfully generates dc power from a 28-GHz wireless power transfer signal, achieving a peak power conversion efficiency (PCE) of up to 18%. Furthermore, it successfully demodulates a range of M-quadrature amplitude modulation (QAM) signals, demonstrating the effectiveness of the proposed design.
