Antenna texts typically derive very complicated functions for the radiation patterns of horn antennas. To do this, first the E-field across the aperture of the horn antenna is assumed to be known, and the far-field radiation pattern is calculated using the radiation equations. While this is con...

It is to be appreciated, however, that other wave equations are equally amenable to the teachings herein. Using the direct boundary element formulation, the acoustic pressure at any point of a homogeneous fluid domain containing no acoustic source can be expressed in terms of the acoustic pressure...
The double ridge antenna[3] is designed using equations in which the dimensions depends mainly on operating frequency of antenna. The results are obtained through simulation by using Ansoft HFSS, a commercially available simulator.Lavanya YChandrakala...
