Nonconformal Discretization of Higher Order vs. IE Method for Multiscale Electromagnetic Scattering
In this work, the nonconformal discretization of volume surface integral equation (VSIE) method comprising surface integral equation (SIE) and volume current integral equation (VJIE) is developed for the calculation of electromagnetic scattering from composite objects with defective meshes. This VSIE allows the discretization of composite objects is non-conformal. That is achieved by introducing half basis functions in VSIE. Further, the nonconformal VSIE is discretized by higher order hierarchical vector (HOHV) basis functions. Because of the hierarchical property of theses HOHV bases, different basis orders based on different mesh sizes and high contrast dielectric medias can be chosen to reduce the matrix dimension and enhance the flexibility of geometrical modeling. Numerical examples of multiscale electromagnetic problems are shown to demonstrate the accuracy, flexibility and ability of the proposed method.
