dc.description.abstract | In this paper a hybrid numerical technique is presented for characterization of the transmission
properties of a three-dimensional slot in a thick conducting plane. The slot is of arbitrary shape and is excited by an electromagnetic source far away from its plane. The analysis of the problem is based on the "generalized network formulation" for aperture problems. The problem is solved using the method of moments(MOM) and the finite element method(FEM) in a hybrid format. The finite element method is applicable to inhomogeneously filled slots of arbitrary shape while the method of moments is used for solving the electromagnetic fields in unbounded regions of the slot. The cavity region has been subdivided into tetrahedral elements resulting in triangular elements on the surfaces of the apertures. Validation results for rectangular slots are presented. Close agreement between our data and published results is observed. Thereafter, new data has been generated for cross-shaped, H-shaped and circular apertures. | en |
