Study on infinite objects' scattering problems

Abstract

The paper analyzes the response of power lines excited by an incident electromagnetic field. A new 2D FDTD method is proposed which analyzes the response of infinite scattering objects excited by electromagnetic waves at an oblique incidence. Maxwell's equations, differential equations and PML absorbing boundary conditions (ABC) are derived. The connecting boundary, where the incident wave is inducted, is computed by the 1D FDTD method. Several numerical calculations of this new FDTD method are provided and compared with the results of transmission line theory, proving the correctness and advantage of this new method.
