Maxwell's equation for a waveguide whose medium has an inhomogeneous dielectric constant is formulated. The resulting modified Helmholtz equation is transformed to a matrix generalized eigen value problem using the method of moments. A complete numerical solution of Helmholtz equation for nonhomogeneous rectangular waveguide has been presented in this paper. This is implemented in MATLAB and the numerical values for the modes of propagation are obtained.

Keywords: Method of moment, anisotropic waveguide, propagation modes, eigen-vector, matrix equation.
