Summary:
The effects of vibrating lossless dielectric medium on the electromagnetic fields were numerically simulated using the method of characteristics (MOC) in one dimension. Comparisons of the computational results of the transmitted and reflected electric fields were carried out and reported in this paper. In this problem there are two types of governing equations that MOC has to solve simultaneously: Maxwell’s equations and Maxwell-Minkowski equations. The former governs when EM fields propagate in free space or in medium at rest whereas the latter rules in moving medium. The computational results reveal the effects of the vibrating medium on the EM fields, which are the direct proof that MOC has successfully solved the Maxwell-Minkowski equations. For the purpose of clear exhibitions the medium was set to vibrate in two different ways, sinusoidal and zigzag which have a maximum instantaneous velocity of 10 % of the speed of light.
