Abstract :
The current distribution on a straight, perfectly conducting thin wire illuminated by a plane wave can be expressed as a sum of traveling current waves. Through the use of a simple model, this traveling wave theory can be extended to finding the current distribution on bent, lossy, loaded thin wires situated in a homogeneous conducting medium. If it is assumed that these waves are TEM (transverse electromagnetic) in nature, familiar transmission line theory can be used to model them. When the effects of radiation loss and mutual coupling are ignored, the expressions are greatly simplified and are surprisingly accurate when compared to a moment method solution. The results obtained from Richmond´s moment method code (1973) and the transmission line model for several cases are discussed.<>
