Calculation of electromagnetic scattering from a dielectric cylinder using the conjugate gradient method and FFT
Abstract
The scattering problem of an axially uniform dielectric cylinder is formulated in terms of the electric field integral equation, where the cylinder is of general crosssectional shape, inhomogeneity, and anisotropy, and the incident field is arbitrary. Using the pulsefunction expansion and the pointmatching technique, the integral equation is reduced to a system of simultaneous equations. A published procedure for solving the system using the conjugate gradient method and the fast Fourier transform (FFT) is generalized to the case of obliqueincidence scattering.
