Abstract :
Electromagnetic transmission into a conducting body through an aperture has been solved using the method of moments. The authors solve a similar problem in which an inhomogeneously loaded open cavity is under external excitation. While a surface-type method-of-moments solution alone is not possible, the finite-element method is combined with the method of moments. To avoid the occurrence of possible nonphysical solutions, the class of tangentially continuous finite elements, or edge elements, and the consistent boundary elements are used.<>
