The problem of a slot associated with a metallic or dielectric hemisph
erical cavity is solved using the method of moments. A computationally
efficient formula is presented for efficient calculations of the admi
ttance matrix. The theory is very helpful to the design engineer as it
involves substantially simpler mathematical calculations.
