COMPARISON OF DIFFERENT GMT-BASED APPROACHES TO CALCULATE THE FIELD DISTRIBUTION IN RECTANGULAR CAVITIES

Abstract

Different GMT based approaches are applied to the problem of field distributions inside shielded rooms. These approaches are discussed and compared by means of modelling, computation time and accuracy of the results compared to a reference solution. The aim is to find a calculation procedure which allows one to compute the frequency behaviour of different test setups and different environment parameters. The usual MMP approach with a special placement of the expansion functions turns out to be the most efficient and accurate way to solve this kind of problem.
