## Field Distributions of High Frequency Waveguide Discontinuities

All field distributions were simulated with the
MAFIA
software package
(version 3.20) which is a multi-purpose ECAD system.
MAIFA
is based
on the Finite Integration Technique (FIT). This technique is the
theoretical basis for solving the Maxwell's equations in integral form. The
analytical equations are discretized onto two grids which are orthogonal to
each other. This yields a set of matirx equations, each of which is the
discrete analogue to one of the original Maxwell equations.
