Problem 2 A transmission line consists of two circular conducting wires as shown below. One wire has radius a and the other wire has radius b. The structure is infinite in the z direction, and the conductors may be assumed to be PEC. a) Find the capacitance per unit length C, between the two conducting wires, assuming that the two conductors are in air. b) Now assume that the same two conductors are immersed in an infinite conducting medium having a conductivity o. Find the conductance per unit length Gi for the transmission line. (This is the conductance per meter in the z direction.) a
