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