Abstract

A procedure to study the electromagnetic (EM) scattering by inhomogeneous structures located in the Fresnel region of aperture antennas is investigated using the finite-difference time-domain (FDTD) method. The Huygen´s sources equivalence principle is used to model the EM fields emanating from these antennas. A large reflector antenna is used to demonstrate the application of this procedure.
