Analysis of Electromagnetic Environment Effect Using TDIE-FDTD-MNA Hybrid Algorithm

It is important but difficult to analyze the electromagnetic environment effect (E3) in the designing of modern airborne, sea, space, and ground systems. Thus a hybrid algorithm of time domain integral equation, finite difference time domain and modified nodal analysis (TDIE-FDTD-MNA) is developed to analyze the E3 of complex systems with cables and nonlinear circuit structures. The plane wave time domain (PWTD) enhanced TDIE method is adopted to solve field problems. The higher order FDTD (2, 4) is adopted to solve cable problems. The MNA is adopted to obtain the response of complex circuits (with nonlinear structures). Numerical examples demonstrate the effectiveness of the proposed algorithm.
