Electromagnetic modeling of composite wire and surface geometries

Interpolation Scheme Based on Adaptive Integral Method for Solving Electrically Large Radiation Problem by Surface/Surface Configuration

“…Thus the complex antennas which involve wire/surface junctions and surface/surface junctions are essential structures for wireless telecommunications. Different methods have been proposed to model the wire/surface junction in order to consider the rapid current distributions around the junction [1][2][3]. However, these models are not suitable to solve radiation problems involving arbitrary 3D conducting objects.…”

Electromagnetic Wave Interaction of Conducting Object with Rough Surface by Hybrid SPM/MOM Technique

“…Simulation techniques for electromagnetic wave scattering by arbitrarily shaped objects in free space are well developed using wire [8][9][10] and surface-patch models [11][12][13][14][15][16][17][18]. The theory and numerical approaches associated with objects near flat interfaces of layered media have also been studied extensively by many researchers [7,[19][20][21][22][23][24][25][26][27][28][29][30].…”

Frequency interpolation methods for accelerating parallel EMC analysis

“…The analyzed model is segmented to triangular or rectangular patch elements or thin wire elements [13]. The surface current on the metal Â × and dielectric Â × and the surface magnetic current Å × on the dielectric are expanded in terms of the basis expansion functions Â Ò , Â Ò and Ã Ò as follows:…”

“…The associated interactions are symmetric, so that, for example, ¼ ´ ¼ µ Ì . Explicit equations of the immittance are shown in [13,11].…”

“…The transmission line approximation method is also employed to take into account the effects of components or subsystems beyond the moment method [13,5]. (typically × ½ ½ × Ò× Ò , and Ò × is small) is a set of sampling frequencies chosen for the analysis.…”
