Electromagnetic inhomogeneous waves at planar boundaries: tutorial

摘要

In this review paper, we summarize the fundamental properties of inhomogeneous waves at the planar interface between two media. We point out the main differences between the wave types: lateral waves, surface waves, and leaky waves. We analyze each kind of inhomogeneous wave, giving a quasi-optical description and explaining the physical origin of some of their properties. (C) 2015 Optical Society of America
