Electromagnetic diffraction on a moving half-plane

TL;DR

This paper investigates how electromagnetic waves diffract on a moving half-plane, revealing that shadow boundaries differ from the stationary case and exhibit unique diffraction phenomena due to motion.

Contribution

It introduces the analysis of electromagnetic diffraction on a moving half-plane, highlighting differences from stationary cases and reporting new diffraction phenomena associated with moving edges.

Findings

Shadow boundaries are not parallel to wave propagation directions.

Diffraction phenomena for moving edges are observed.

Differences from stationary diffraction cases are demonstrated.

Abstract

A problem of electromagnetic (EM) plane wave diffraction on a moving half-plane in a homogeneous and isotropic medium is considered. It is shown, that unlike the stationary case, the shadow boundaries of the incident and reflected wave are not parallel to propagation directions of those waves. Other diffraction phenomena reported earlier for objects with moving edges, are also observed here.
