Multi-solver schemes for electromagnetic modeling of large and complex objects
… scheme, in which the Rao-Wilton-Glisson and the Buffa-Christiansen functions are both employed as the testing functions, is first presented to improve the accuracy of the FE-BI method. An efficient absorbing boundary condition (ABC)-based preconditioner is then proposed to accelerate the …

Accuracy improvement of the second-kind Fredholm integral equations in computational electromagnetics
… error of the identity operators by using the Buffa-Christiansen (BC) functions as the testing function, leading to much more accurate solutions to the second-kind integral equations for smooth objects in both perfect electric conductor (PEC) and dielectric cases, while maintaining their fast …
