Solutions of large integral-equation problems with preconditioned MLFMA
We report the solution of the largest integral-equation problems in computational electromagnetics. We consider matrix equations obtained from the discretization of the integral-equation formulations that are solved ...
Extending the applicability of the combined-field integral equation to geometries containing open surfaces
(Institute of Electrical and Electronics Engineers, 2006)
In this letter, we consider the solution of large electromagnetics problems of composite structures with coexisting open and closed conductors. By modifying the construction of the combined-field integral equation (CFIE), ...
Iterative solutions of hybrid integral equations for coexisting open and closed surfaces
