Abstract

By modeling a wire-wound coil as an anisotropically conducting cylindrical boundary, one may start from Maxwell\´s equations and deduce the structure\´s resonant behavior. Not only can the propagation factor and characteristic impedance be determined for such a helically disposed surface waveguide, but also its resonances, "self-capacitance" (so-called), and its voltage magnification by standing waves. Further, the Tesla coil passes to a conventional lumped element inductor as the helix is electrically shortened
