| Popis: | In this paper we investigate the penetration of both E and H waves into a cylinder of arbitrary cross section (characteristic dimension L). The material of the cylinder is a nonmagnetic good conductor, and we examine the limits of deep penetration (small L//spl delta/, where /spl delta/ is the penetration depth) and small quality factor Q=(/spl omega//spl epsiv//sub 0///spl sigma/). These two asymptotic conditions imply a low-frequency situation, for which we derive formulas for the induced currents and associated Joule and radiation losses. |
