Electromagnetic Properties from Moving Dielectric in High Speed with Lorentz-FDTD

A novel Lorentz finite-difference time-domain (FDTD) method was proposed to analyze scattered fields from moving complex dielectric in this letter. Different from other methods, we present a special way to introduce the incident plane wave in the moving system. The scattered fields are transformed from the moving system to the rest of the system with the Lorentz transformation and linear interpolation technique. Numerical results verify the accuracy and validation of the proposed method to calculate scattered fields from moving dielectric slabs.
