Abstract
A numerical approach is presented for the analysis of reflected fields from a moving conducting surface by the finite-difference time-domain (FDTD) method combined with boundary conditions of moving boundaries. Based on the scattering model, boundary conditions of moving boundaries are implemented into the FDTD algorithm. In the computation region, equations of moving boundary conditions are substituted for FDTD difference equations to solve electromagnetic fields at the moving surfaces. The reflected waves from one-dimensional conducting surface are analyzed, which moves towards and against the excitation source at a high speed. Compared with the amplitude and frequency of the incidence wave, those of the reflected waves from the moving conducting surface suffer a modulation shift. By comparison, results simulated in this paper are in good agreement with existing analytical results.
