The scattered field, when a plane wave is incident along the axis of a slotted, perfectly conducting, semi‐infinite cone, is obtained by a superposition of the scattered field from an unslotted cone and the radiation field from the slot on the cone. The slot is a finite, thin, circumferential slot backed by a cavity which is characterized by an admittance. The induced voltage is represented by a sinusoidal distribution. The amplitude of the induced voltage is then related to the incident field by expressing it in terms of the radiating and load admittances of the slot. Expressions for the radiation admittance and the scattered far fields are derived.
