Generalized excitations and loads for electromagnetic analysis with boundary elements

摘要: Abstract Several new excitation and load models are proposed for electromagnetic analysis in the context of a Galerkin-type large-domain (higher-order) boundary element method (BEM) or Method moments structures composed thin wires, metallic surfaces, imperfect inhomogeneous dielectric bodies. The represent natural generalization point-delta generators loads wires. They used loading quadrilateral surface elements hexahedral volume elements, termed line-delta surface-delta loads, respectively. corresponding Galerkin generalized impedance voltage matrix derived incorporated BEM outlined paper. accuracy usefulness illustrated on number characteristic examples. It is believed that these can also be included other BEMs systems frequency domain with comparable advantages.
