Efficient Solution of the Differential Form of
Maxwell's Equations in Rectangular Regions

Abstract-One of the problems of the finite element and the
finite difference method is that as the dimension of the problem
increases, the condition number of the system matrix increases
as e(1/h2) (of the order of h2, where h is the subsection
length). Through the use of a suitable basis function tailored for
rectangularregions, it is shown that the growth of the condition
number can be checked while still retaining the sparsity of the
system matrix.This is achieved through a proper choice of entire
domain basisfunctions.Numerical exampleshave been presented
for efficient solution of waveguide problems with rectangular
regions utilizing this approach.
I. INTRODUCTION
HE finite difference [l] and the finite element method
T[2] have been developed over the last few years in the
microwave area for efficient solution of the differential form
