Publisher's Synopsis
Excerpt from Excitation of Surface Waves on an Unidirectionally Conducting Screen by a Phased Line Source
Here k is the free Space propagation constant in the medium. Note that when B O, the charge density is zero and the source becomes a Simple line current. The electric and magnetic fields Simplify accordingly. We consider the more general case of a variable (or phased) line source since surface waves arise on the screen. When the source is a simple line current element without a charge distribution superimposed along its length, surface waves arise only if the source is skew with respect to the screen. This is the case considered by Seshadri us].
