Uniform Plane Waves - Rutgers University
www.ece.rutgers.eduUniform Plane Waves 2.1 Uniform Plane Waves in Lossless Media The simplest electromagnetic waves are uniform plane waves propagating along some fixed direction, say the z-direction, in a lossless medium {,μ}. The assumption of uniformity means that the fields have no dependence on the transverse coordinates x,yand are functions only of z,t.
