Mathematical Analysis of RDRA Amplitude Coefficients

Abstract

Mathematical analysis of amplitude coefficients in rectangular DRA (RDRA) have been evaluated. Rigorous theoretical analysis has been developed for different resonant modes inside RDRA. The resonance phenomenon and its potential use as radiator have been described. The dielectric polarization P is equal to the total dipole moment induced in the volume of the material by the electric field. The discontinuity of the relative permittivity at the resonator surface allows a standing electromagnetic wave to be supported in its interior at a particular resonant frequency, thereby leading to maximum confinement of energy within the resonator. Certain field distributions or modes will satisfy Maxwell’s equations and boundary condition. Mathematical solution to get amplitude coefficients C _mnp along with its phase coefficients has been obtained. These are also known as eigenvector.
