Representation of wave fields in a graded multilayer medium (2405.16998v1)

Published 27 May 2024 in physics.optics, math-ph, math.MP, and physics.class-ph

Abstract: In this work we present a new approach in representation of wave fields in nonuniform 1-D multilayer medium. This approach is based on the use of a modified homogeneous basis. A new form of coupled equations for describing nonuniform one-directional photonic crystals is proposed. This description can be especially useful to study radiation that originates when fast electrons move in such medium
