Abstract
An interface-enriched generalized finite-element method (IGFEM) is presented for accurate and efficient electromagnetic analysis of complex composite materials. Without using meshes that conform to the material interfaces, the IGFEM enriches the solution space at the material interfaces to capture the discontinuities of the field and its derivatives. Two verification examples and one engineering problem are provided to respectively demonstrate the accuracy of the IGFEM and its potential in modeling composites with intricate and randomly distributed internal structures.
