Interestingly, many such problems can be recast to be solved by quantum annealing. Quantum annealing, a kind of quantum computer, utilizes quantum tunneling for state transitions, which enables one to find the global minimum in a complex energy landscape. Part I of this article explains quantum annealing for the classical electromagnetic community, assuming little knowledge of quantum theory. Both the basic principle and recent developments to extend its applications, such as hybrid quantum–classical annealing, are reviewed. Part II presents various examples of electromagnetic problems that can be solved by quantum annealing. Those are 1) optimization of a reconfigurable directional metasurface, 2) finding current distribution in an arbitrary wire antenna, 3) finding charge and field distributions in a static condition, and 4) optimization of source excitation to focus fields in hyperthermia. Finally, the performance of quantum annealer is compared with classical solvers to deduce the type of application in which a quantum annealer of current technologies can be preferred in practice.","PeriodicalId":13090,"journal":{"name":"IEEE Antennas and Propagation Magazine","volume":"68 1","pages":"37-46"},"PeriodicalIF":3.6,"publicationDate":"2026-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148483508","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

They have the ability to produce multiple directive beams that can cover a predefined angular range. Among different multibeam antennas, gradient-index (GRIN) flat lenses serve as a promising technology to realize multibeam radiation with their advantages of low profile, easy installation, low cost, high efficiency, and a wide beam coverage. This article describes the recent advances in GRIN lens antennas. In particular, this article presents a novel 3D-printed multibeam GRIN lens antenna. The design offers a broad 2D angular coverage of ±45°. It maintains a scanning loss of less than 2.4 dB and sidelobe levels (SLLs) below –10 dB. The antenna also achieves a high aperture efficiency of up to 60% across the 12–15-GHz frequency band.","PeriodicalId":13090,"journal":{"name":"IEEE Antennas and Propagation Magazine","volume":"68 1","pages":"47-58"},"PeriodicalIF":3.6,"publicationDate":"2026-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=11128932","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148481962","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These static phantoms, while reproducible, overlook critical factors, such as tissue heterogeneity, implantation depth variability, and motion-induced transmission fluctuations, leading to unreliable performance estimates for deeply implanted medical devices. To address this, we propose a hybrid experimental method combining a customizable tissue-mimicking gel phantom (fabricated using water, sugar, salt, and agar shaped in 3D-printed molds) with a living human subject. By employing a mobile setup with rotational freedom, we capture real-world channel gain and untethered received signal strength indicator (RSSI) variations, revealing a 20-dB disparity between line-of-sight (LOS) and non-LOS (NLOS) conditions, a critical metric undetectable with conventional bench-top phantoms. This approach bridges the gap between controlled lab testing and clinical realism for implantable antenna design, allowing surgery and animal-free implantation estimates.","PeriodicalId":13090,"journal":{"name":"IEEE Antennas and Propagation Magazine","volume":"68 1","pages":"62-115"},"PeriodicalIF":3.6,"publicationDate":"2026-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148482776","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
