One-Dimensional Numerical Solution of the Maxwell-Minkowski Equations

並列摘要


In this paper the author demonstrates one-dimensional numerical simulation results of the propagation of electromagnetic pulses onto a dielectric slab that is moving with a constant speed. The Maxwell-Minkowski equations are numerically approximated using the characteristic-based method. The effects of the moving dielectric slab on the reflected, transmitted electric fields and that inside the dielectric slab for various velocities are illustrated and compared based on the stationary slab case. The frequency-domain results are obtained through Fourier transform of the time-domain data. The medium used in the numerical model is assumed to be infinite, homogeneous, isotropic, lossless, 50 cm thick, and have a dielectric constant of 4. The dielectric slab is set to move either toward or away from the incident electromagnetic pulse with a constant speed of 10 percent of the light speed.
