The penetration of fields through an infinite slot in a conducting plane backed by a channel is examined. The total field in the interior of the channel and above the conducting plane is determined by two independent integral equation methods: (1) coupled integral equations which can be used to determine the fields for a channel with an arbitrarily shaped cross section and (2) a single integral equation which involves a Green's function specific to the shape of the channel. Data from the two methods are presented for the equivalent currents obtained from the integral equations, for the fields near the channel‐backed slot, and for the actual currents present on the conducting surfaces. Methods for determining the currents and fields for the case of a transverse‐electric‐to‐slot‐axis excitation were presented in part 1. This second part focuses on the development of techniques for determining fields and currents in cases where the excitation produces a field that is transverse magnetic to the slot axis.
