Abstract

The complex nature of solving microwave circuit problems with their many varied boundary conditions, precludes direct analysis utilising the basic laws involved. This thesis describes methods that have been developed to determine the defining parameters of such problems. The methods are based on numerical techniques, using a digital computer to perform the calculations.

The finite difference and element techniques are reviewed briefly and extensions made into the analysis of three dimensional configurations. The difficulties of such methods are also discussed. The evolution of the steady state transmission line element method from the finite difference/element techniques is shown to possess many distinct advantages over the more conventional techniques, notably that of the ease in which it is formulated.

Examples of rectangular, circular and elliptical-wave guide analysis are shown, and comparisons formed with finite difference/element analysis where necessary. Proposals are also introduced whereby the method may be utilised to provide a wide range of microwave characteristics, with little or no alterations to existing procedures. The adaptation to other fields of interest, such as those associated with structural or fluid dynamics was also briefly noted.
