Abstract:

New algorithms for the time domain analysis of electromagnetic waves in shielded structures are presented. Electromagnetic fields inside a structure under investigation are expanded into series of basis functions and the expansion coefficients are found by means of the Method of Moments. Numerical cost of algorithms and their stability is discussed and cost efficient hybrid approach combining the new technique with a classical FDTD algorithms is proposed. Numerical tests are showing that significant speed up can be obtained for structures with homogeneous regions. A very fast, low return loss absorbing boundary condition ABC is proposed which accounts for the highly dispersive character of the structure. A very good performance of the ABC is demonstrated.
