ScholarBank@NUS Repository. https://doi.org/10.1109/8.997985||Abstract:||The Formulation-C Green's functions for multilayered media are reformulated in this paper to extract z-dependent part when the source and observation points are in different layers. Discrete complex image method (DCIM), is applied to obtain complex images independent on z but dependent on z′. For simulation of three-dimensional (3-D) perfectly electrical conduction (PEC) objects penetrating two or more layers, tables of complex images are built in a z′-grid. During the matrix-filling stage of mixed-potential integral equation, together with method of moments (MPIE-MoM), the spatial-domain Green's functions are interpolated from values in the z′-grid, while these values are calculated from complex images in the z′ grid. This interpolation scheme is more efficient than those directly storing the spatial-domain Green's functions. Numerical examples are given for analyzing a dipole in a two-layered media.||Source Title:||IEEE Transactions on Antennas and Propagation||URI:||http://scholarbank.nus.edu.sg/handle/10635/55128||ISSN:||0018926X||DOI:||10.1109/8.997985|
