Abstract
An alternative and more efficient method for computing electromagnetic fields in arbitrarily-shaped inhomogeneous dielectric bodies is presented. In this method, a transpose-free quasi-minimal residual (TFQMR) algorithm is employed to avoid the complicated multiplication between the transpose of the system matrix and vector, resulting in a much simpler computer implementation. The number of the fast Fourier transforms (FFT) is reduced to only six per iteration. The TFQMR-FFT method yields excellent results even for highly inhomogeneous dielectric objects.
