✦ Synopsis

In previous work novel, techniques with general applications were used to define the transmission line parameters within two-and three-dimensional orthogonal curvilinear meshed space. This paper presents a specific application of the technique and demonstrates that considerable savings in computational load can be achieved when our meshing scheme is applied to 3D electromagnetic problems which are described using the TLM symmetrical super condensed (SSCN) node. Results have been validated using two types of resonant cavity. A comparison of dominant modes confirms that the use of orthogonal curvilinear mesh yields closer agreement with analytical results (using fewer nodes) than would be possible with conventional meshing techniques.
