Optimized hierarchical higher-order vector basis function for 3-D electromagnetic scattering

The method of moment based on optimized hierarchical Higher-order vector basis function on curvilinear triangular patch is presented for 3-D electromagnetic scattering. The numerical performance of the optimized hierarchical vector basis function is investigated and compared with the interpolatory vector and traditional hierarchical vector basis functions, demonstrating the advantage of optimized hierarchical higher-order vector basis function in efficiency and flexibility.
