Electromagnetic field boundary conditions on moving interfaces in high frequency case

Abstract

The electromagnetic properties of the moving media interface in a high frequency range is analysed and the dependence of generalized refraction on frequency is obtained based on special relativity.

Variational Analysis of High-Frequency Effect on Moving Electromagnetic Interface

“…To analyze the relativistic situation, the frames of 𝑆 ′ and 𝑆 should be established. [34,35] Physically, the evolution of the ray pulse has the spherical symmetry in the medium at rest with respect to the 𝑆 ′ frame. In the case of a moving medium, the evolution of the ray pulse is dragged to an expanding ellipse in the moving medium of the 𝑆 fame.…”

“…Clearly, the basic principle supports the generalized way to investigate the related performances on the moving boundary further. Hence in this work, with the assistance of our forgoing theoretical study, [35] a unified and concisely practical model is established for the transmission of high-frequency electromagnetics on the moving interface in the unified manner of variational. In the model, the movement influence is considered under the condition of special relativity.…”
