AB  - A novel entire-domain finite element technique based on curvilinear hexahedral geometrical modeling using B-splines in conjunction with higher order hierarchical polynomial curl-conforming vector basis functions for field expansions is proposed for electromagnetic analysis of microwave devices. The effectiveness of the technique is evaluated in analysis of microwave cavities and it is compared with alternative reference solutions and with HFSS. Examples demonstrate large single-element (entire-domain) models with p-refined field distributions and better accuracy in curvature modeling than with the Lagrange interpolation. Extraordinary flexibility of the B-spline hexahedral elements, combined with higher order field expansions, allows accurate modeling of complex structures with sharp edges using a single finite element.

AB  - Parallelization of time-consuming volume integrations in the matrix filling is performed using OpenMP to provide a smooth transition of a higher order finite element method (FEM) code for electromagnetic analysis to the multi-core hardware architecture. In the process, the carefully constructed original computational scheme suited to maximally avoid the redundant computations in the higher order FEM is not affected. The results, in analysis of an electrically large dielectric scatterer, demonstrate acceleration of up to 2.28 times in a four-thread architecture.
