Receiving Characteristics of Impedance Loaded Slot Configurations

A general theory is developed for determining the current in the load impedance of any slot configuration in terms of the current in the load impedance of the complementary strip (wire) circuit. It is assumed that these duals are illuminated by plane wave electromagnetic fields. Following establishment of the procedures and techniques for analysis of strip and slot circuits, the practical situation presented by a bomb in the open bomb bay of an aircraft with load impedance connected between one end of the weapon and fuselage is treated. The load current is found approximately when the incident plane wave electric field is polarized in both transverse and longitudinal directions with respect to a strip that is equivalent electrically to a specific right circular cylinder that represents the weapon.
