Abstract

A new Lorentz-FDTD method is proposed to analyze scattering fields of moving conducting bodies in this paper. The transformation formulas of electromagnetic field components, space components and time variable are discussed by using Lorentz transformation between two inertial systems. The total-field scattering-field boundary condition is built to introduce an incident plane wave in the rest system of moving bodies. The reflection wave of one dimensional moving conducting surface is simulated with the proposed Lorentz-FDTD method. Numerical results show that the reflection wave suffers a frequency shift. Also, the range of frequency shift is a function of the moving velocity of bodies.
