Analysis of MoM/FDTD hybrid technique on shortwave antenna in complex environment

Abstract:

This paper adopts the Method of Moment/ Finite Difference Time Domain(MoM/FDTD) hybrid technique in computational electromagnetism for analyzing the problems of shortwave antenna in complex environment. The models of shortwave dipole antenna in free space and on the ground are built, and the numerical simulation of the models is programmed with the hybrid technique. The comparison between the computing result by the hybrid technique and the result in the reference demonstrates the validation of the technique. Some good experiences are presented for improving shortwave antenna.
