(4 pts) Prob. 3 Determine the inductance per unit length for the parallel plate transmission line shown. Assume the transmission line is of infinite length in the z direction and ignore fringing fields. The plate spacing is d and w >> d. The plates are parallel to the xy-plane and the current flow is in the -a, direction on the top plate and the +a, direction on the bottom plate. Assume free space between the plates.
