However, conventional optimizations of the transmitter (Tx) coils begin with a limited set of regular shapes, resulting in suboptimal solutions in terms of efficiency and uniformity. This article proposes a novel optimization framework for obtaining the optimal Tx designs without a predetermined coil topology. The coil is modeled as linear expansions of basis surface current density (SCD) modes, and a circuit-electromagnetic (EM) field combined analysis is proposed to associate the transmission efficiency with the EM fields. With the proposed scheme, the optimal tradeoff between transmission efficiency and magnetic field (<italic>B-field) spatial uniformity can be found, and customizable according to application needs. A demonstrative platform for freely behaving small animals is set up to validate the proposed method, where three Tx coils are optimized for maximum efficiency with <italic>B-field uniformity of 90% along <italic>x- and <italic>y-axes and 97% along the <italic>z-axis. About 5%–10% transmission efficiency can be achieved inside the spherical shell using a single Rx coil at the measured points. The magnetic field measurement is in good agreement with the simulation results. The proposed method is suitable for the optimization of Tx coil designs for wireless headstage platforms and other consumer applications.","PeriodicalId":13102,"journal":{"name":"IEEE Transactions on Antennas and Propagation","volume":"73 9","pages":"6562-6573"},"PeriodicalIF":5.8,"publicationDate":"2025-06-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145050840","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}

Considering the path loss and the TA element’s pattern, the optimum radiation pattern of the feeding source is required to follow the <inline-formula> <tex-math>$sec^{3}theta $ </tex-math></inline-formula> in the radiated angular to enhance the illumination efficiency and vanish quickly out of the radiated angular to enhance the spillover efficiency. To realize the optimum pattern, a <inline-formula> <tex-math>$2times 2$ </tex-math></inline-formula> magneto-electric (ME) dipole antenna array is used as the basic structure to provide a proper gain with identical beamwidth in evaluation planes. Then, a superstrate loaded by airholes is placed above the array to mimic the optimum pattern. To validate this method, a prototype operating at 28 GHz is designed, fabricated, and measured. Measured results show that the prototype can achieve a peak gain of 29.1 dBi and peak aperture efficiency of 72.7%. The obtained 1- and 3-dB gain bandwidth is 11% and 25%, respectively. Since the prototype enjoys high aperture efficiency, low sidelobe levels, and simple structure, it is a promising candidate for future point-to-point wireless communication systems.","PeriodicalId":13102,"journal":{"name":"IEEE Transactions on Antennas and Propagation","volume":"73 9","pages":"6949-6954"},"PeriodicalIF":5.8,"publicationDate":"2025-06-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145027976","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 learning-based induced current inversions, the deterministic part of the induced current is usually extracted from the measured scattered field and used as input to a neural network for predicting the total current. However, this approach relies solely on the neural network’s function approximation capability, which limits its generalization ability and accuracy. To address these limitations, this communication proposes a variation-based residual learning (VBRL) method. Starting with the deterministic current, a variational current is derived from the variation of the scattered field. This variational current is then used to update the deterministic current, providing a refined input for a neural network. To reduce the network’s fitting burden, a residual learning scheme is adopted, where only the residual part of the current is predicted. The total induced current is then obtained by summing the predicted residual current with the input current. In our implementation, both the variational operation and residual learning are encapsulated within a VBRL module, and multiple VBRL modules are cascaded to iteratively refine the solution for higher accuracy. Numerical results demonstrate that the proposed VBRL method achieves superior accuracy and generalization ability compared with existing learning-based approaches, with a comparable inversion time.","PeriodicalId":13102,"journal":{"name":"IEEE Transactions on Antennas and Propagation","volume":"73 9","pages":"6961-6966"},"PeriodicalIF":5.8,"publicationDate":"2025-06-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145027953","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}

When the radiated field is generally given by cylindrical Hankel harmonics, the steepest descent method in the complex plane is adopted to study the Hankel function that can be rewritten as an asymptotic series expansion expression. Furthermore, the single-cut radiated field can be rewritten as a series of spherical waves with different expansion orders, where the first-order coefficient exactly corresponds to the far-field radiation pattern. More importantly, far-field pattern and its derivative function completely determine the high-order expansion coefficients, yielding another mathematical relationship between the near field and far-field. Finally, based on the different forms of the derivative function, the far-field can be directly solved from the near-field sampling data, which is obviously different from the existing transformation methods relying on intermediate variables like Fourier coefficients. Besides, the presented method not only outperforms the conventional Fourier method in the presence of spatial truncation, but also provides another mathematical derivation for the existing Wilcox expansion which is then applied to the near-field measurement. Thus, the study indicates an intrinsic mathematical structure of the radiated field, showing great theoretical significance and application prospects.","PeriodicalId":13102,"journal":{"name":"IEEE Transactions on Antennas and Propagation","volume":"73 9","pages":"7063-7068"},"PeriodicalIF":5.8,"publicationDate":"2025-06-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145036991","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}

Recently, artificial neural networks (ANNs) have been employed to accelerate this method by rapidly predicting the expansion coefficients of SED basis functions without filling mutual coupling matrices. However, the training processes of prediction models can be further improved due to its classical computational paradigm. In this article, a novel variational quantum algorithm (VQA) enhanced SED basis functions method is proposed and the quantum computing paradigm is utilized to analyze LFPSs for the first time. In our algorithm, the array features are expanded and encoded onto few qubits, and the resulting quantum state is unitarily transformed into expansion coefficients by the parameterized quantum circuit. In addition, the algorithm is deployed on the quantum simulator for numerical experiments. The experimental results demonstrate that our method can accurately and quickly analyze LFPSs. Furthermore, the quantum-inspired models achieve 27%–62% improvements in learning efficiency for corner and edge cells (ECs), and 22%–59% improvements in robustness for all types of cells.","PeriodicalId":13102,"journal":{"name":"IEEE Transactions on Antennas and Propagation","volume":"73 9","pages":"6707-6717"},"PeriodicalIF":5.8,"publicationDate":"2025-06-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145050818","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}
