An efficient method for analysis of the ultra-wide band (UWB) antenna is proposed, the UWB microstrip antennas are analyzed by the mixed potential integral equation (MPIE). The produced dense impedance matrix is partitioned and compressed hierarchically by the multilevel UV method. And the linear systems are solved by the generalized minimal residual method (GMRES) iterative solver, the required matrix-vector...
In this article, the planar layered finite frequency selective surface (FSS) is analyzed by the mixed potential integral equation. The multiresolution (MR) preconditioned multilevel UV method is applied to accelerate the matrix‐vector multiplication. The MR preconditioning technique is based on the construction of MR basis functions, which are constructed as linear combinations of Rao‐Wilton‐Glisson...
