摘要
电磁环境效应是在现代航空、航海、航天以及地面系统设计中必须考虑的因素。针对带有线缆结构的复杂系统的电磁环境效应问题,发展了一种时域积分方程(TDIE)和时域有限差分(FDTD)的混合方法,采用时域平面波(PWTD)加速的TDIE方法求解场问题,高阶FDTD(2,4)方法求解线缆响应。数值算例表明了方法的有效性。
Electromagnetic environment effect (E3) must be considered in the design of modern aviation,navigation, spaceflight and ground systems. Aiming at the problem of the E3 in complex systems with cable structures,a time domain inte-gral equation and finite difference Time domain(TDIE-FDTD)hybrid algorithm is developed. The TDIE method accelerated by plane wave time domain(PWTD)is adopted to solve field problems,a higher order FDTD(2,4)is adopted to solve cable re-sponse. Numerical examples demonstrate the effectiveness of the proposed algorithm.
