Loss power in copper walls of a Fabry-Perot resonator. Consider a Fabry-Perot resonator, in Fig. 10.3, with a standing plane electromagnetic wave given by Eqs. (10.9), where Ei0 = 100 V/m, = 102 rad/m, and = 1010 rad/s. In addition, let the length of the resonator be a = 3 cm, and let its walls be made of copper ( = 58 MS/m and = 0) and its dielectric be nonmagnetic. Under these circumstances, compute the time-average power of Joule's losses in the resonator per S = 1 cm2 area of its surface (viewed across both walls)
