摘要
An impulse plane wave is introduced in Lorentz finite-difference time domain for calculating the fields of high-speed moving dielectric. Applying the impulse plane wave and the fast Fourier transformation, we can directly read out the frequency shifts of the reflected and transmitted waves by one-time calculation. The proposed approach can greatly save run time and enhance the computation efficiency, especially in terms of considering a large number of incident frequencies. Two cases of moving canonical and non-canonical dielectric targets are considered to verify the accuracy and validity of the proposed method.
