境界要素法による三次元電磁界解析

Boundary element methods for three-dimensional electromagnetic field analysis are overviewed. Boundary element method is categorized into integral equation method and characterized by mathematical formulation procedure based on the Green\u27s theorem. The boundary element methods for electromagnetic field analysis are formulated by using the Maxwell\u27s equations, in which magnetic field and electric field are related each other and expressed by vector operations. In this paper, surface charge method for electrostatic ploblems, boundary element method using unknown magnetic flux density for magnetic flux density and electric field for eddy current problems, and moment method for electromagnetic wave problems are described as practical boundary element methods and computation results by the methods are shown
