时域电磁散射问题的时域积分方程方法研究及其应用探索

The Bachelor Thesis of the University of Electronic Science and Technology of China explores the increasingly active research area of time-domain integral equation methods for analyzing transient electromagnetic scattering problems. Focusing on the time-domain integral equation time-stepping algorithm and its fast algorithms, this thesis investigates the numerical implementation techniques, issues of late-time stability, and acceleration of calculations using a two-layer plane wave algorithm. The study is divided into four main sections, emphasizing the importance of adapting to the growing demand for wideband signals and nonlinear system engineering applications. The research findings contribute to the understanding of time-domain electromagnetic scattering, time-domain integral equations, time-stepping algorithms, late-time instability, and time-domain plane wave algorithms. This thesis serves as a valuable resource for researchers and engineers in the field of electromagnetic scattering and transient dynamics.
