Very-high-order CEM modeling

According to the higher order or large-domain (entire-domain) computational electromagnetics (CEM) approach, a structure is approximated by a number of as large as possible geometrical elements, and the approximation of current/field components within individual elements is in the form of a single (one-, two-, or three-fold) functional series of a sufficiently high order. This approach can greatly reduce the number of unknowns for a given problem and enhance further the accuracy and efficiency of the analysis in practical applications. This paper reviews very-high-order techniques for analysis of electromagnetic problems developed in our group over the past ten years and presents some recent advances.
