Systems and methods for electromagnetic field analysis

Abstract:

Systems and methods are provided for analyzing an electromagnetic field in an original domain. An original domain is decomposed into one or more finite-element-boundary-integral (FEBI) regions and one or more integral-equation (IE) regions. A model is determined for an electromagnetic field in the one or more FEBI regions and the one or more IE regions. An initial block system matrix for the original domain is generated based at least in part on the model. The initial block system matrix includes a first diagonal block corresponding to the one or more FEBI regions and a second diagonal block corresponding to the one or more IE regions. A replacement matrix is generated based at least in part on a physical optics (PO) method. A final block system matrix is generated by replacing the second diagonal block in the initial block system matrix with the replacement matrix.
