Abstract

The gain properties of an axially slotted cylinder coated with two lossless layers and embedded in a certain lossless background medium have been investigated analytically. The effects of different types of coating layers, i.e. dielectric, magnetic, and Single Negative materials upon the gain characteristics of an axial slot have been discussed. It is observed that if inner layer is either of dielectric or magnetic type and outer layer is an Epsilon Negative type having its relative permittivity of negative one and slotted cylinder is embedded in the free space then the gain has directive pattern. It is also studied that if both layers are dielectric or magnetic types and embedded in a Mu Negative medium then its gain pattern becomes more directive with the maximum gain in the forward direction.
