Wavenumbers for currents on infinite- and finite-length wires in a chiral medium

An attempt is made to determine the wavenumbers of the current waves excited on wire antennas located in an infinite chiral medium using two complementary approaches. One is an extension of an existing computer model (NEC) (see G.J. Burke and A.J. Poggio, 1981) that permits the modeling of arbitrary wire objects located in an infinite chiral medium. The other involves the development of a solution to an infinitely long cylindrical antenna, also located in an infinite chiral medium. The latter canonical problem is of interest in its own right, and it provides as well a means for achieving mutual validation with the NEC model.<>
