Electromagnetic axially symmetric excitation of a finite cone by the ring slot

The scattering of the axially symmetric TM-wave by the finite cone is investigated using the analytical regularization method. The characteristics of the far field pattern and the distribution of the electromagnetic energy emitted by the slot located on the conical screen are analysed. The physical effects connected with electromagnetic wave radiation by the electrodynamic system ldquofinite cone-slotrdquo are studied.
