A transmission line consists of two identical wires of radius a,?separated by distance d?as shown in Figure. Maintain one wire at 1 V and the other at ? 1 V and use MOM to find the capacitance per unit length. Compare your result with exact formula for C?in Table 11.1. Take a =?5 mm, d =?cm, ? = 5 m, and e = ?_o.
