Abstract

Perfect Matched Layer (PML) and Convolutional PML boundary conditions are used in FDTD for Radar Cross Section (RCS) calculation of a perfect electric conducting (PEC) sphere. Matlab is used for coding the FDTD. The results obtained are compared with that of results obtained using FEKO full-wave electromagnetic simulation software. It is seen that the CPML boundary condition takes less simulation time with the smaller computational domain without compromising accuracy.
