Multi-domain pseudospectral time-domain method for lossy media

Fan, G.-X. ; Liu, Qing Huo ; Hesthaven, J. S.

Multi-domain psuedospectral time-domain (PSTD) algorithm was studied to model electromagnetic scattering from two-dimensional buried objects in lossy media. The algorithm was applied to model various ground penetrating radar system applications involving interfaces of arbitary shape in a lossy half space. Results demonstrated the effectiveness of multi-domain PSTD algorithms as a high-order time-domain solver for Maxwell equations.
