报告摘要：
近年来，特征模理论（TCM）因其强大的优势在电磁学领域备受关注——它无需考虑特定激励源，就能为确定任意形状物体的谐振特性、获取其模态解提供便捷方法。特征模最早由加尔巴茨和哈林顿等人于20世纪70年代左右提出并求解，当时主要针对理想导电体。近年来，经过众多学者的深入研究，特征模理论已拓展至不同材料构成的各类结构，且发展出多种积分方程形式。如今，它已成为分析电磁结构的有力工具，能更清晰地揭示电磁物理本质。本次报告旨在探讨如何将特征模理论应用于复杂电磁结构的设计，例如平台集成天线、复杂背景环境下的天线以及具有特殊用途的新型电磁结构等，并展望特征模理论可能助力的其他研究方向。
Recently, theory of characteristic modes (TCM) attracts much interest in electromagnetism due to its strong ability to provide a convenient approach to determine the resonant behavior and get the modal solutions of arbitrarily-shaped objects, without considering specific excitation sources. The characteristic modes (CMs) were first defined and solved for perfectly electrically conducting (PEC) bodies by Garbacz et al. and Harrington et al. in around 1970s. Through much more efforts in developing the TCM for different structures consisting of different materials using different forms of integral equations, TCM has become a powerful tool for analyzing electromagnetic (EM) structures with clearer EM physics. This talk aims to address how to apply TCM to the design process of EM structures, such as platform integrated antenna design, antenna with complex background, and novel EM structures with special purposes, followed by possible areas that TCM can help.
