pp: 122-126A Comparison of Performance of Four Methods in Solving Time Domain Integral Equations for Arbitrarily Shaped Conducting BodiesXinpu Guan, Shaogang Wang, Yi Su, and Jun-Jie Mao doi:10.2529/PIERS060906091850 Downloads: 913 Abstract:The objective of this paper is to generate a temporal response of three dimensional conducting structures by solving time domain electric-field integral equation. Four methods including Initial MOT/ averaging MOT/ IMPT/ MOO are used to solve the integral equation. Comparison of performance of four methods is presented to illustrate validity for solving late-time instability by simulation of four targets including two simple and two complex conducting bodies.References:1.
