Leaky Waves: Principles and Applications

Abstract

Here, inhomogeneous waves, and, in particular, leaky waves are initially described and natural phenomena that can be expressed in terms of inhomogeneous improper waves are also introduced. The description of the physical properties of inhomogeneous waves and leaky waves and their physical characteristics will finally allow us to describe the propagation features and the radiation patterns generated by leaky‐wave antennas (LWAs), as they are conventionally defined in terms of leaky waves. Furthermore, this chapter will go into the description of LWAs families and features.
