Analysis of a Rectangular Waveguide Using Finite Element Method

Progress In Electromagnetics Research C, Vol. 2, 117-125, 2008
Abstract
The characteristics impedance of the fundamental mode in a rectangular waveguide is computed using finite element method. The method is validated by comparison with the theoretical results. In addition to this, we have considered the problem of determining the modes of propagation of electromagnetic waves in a rectangular waveguide for the simple homogeneous dielectric case. The starting point is Maxwell's equations with an assumed exponential dependence of the fields on the Z-coordinates. From these equations we have arrived at the Helmholtz equation for the homogeneous case. Finite-element- method has been used to derive approximate values of the possible propagation constant for each frequency.
