Abstract

Abstract: The paper investigates eigen modes of the wave equation in discontinuous media and explores the underlying physical mechanism. We also study the reflection and transmission of wave at the interface and reveal a full transmission effect under specific physical conditions. This effect may find applications in wave-absorptive materials.

Key words: wave equation, interface, eigen mode, half-wave loss, full transmission
