| Popis: | The Lebedev grid is an alternative to Yee grid where, because the discretized fields lie at the same location in space, there is no need for further field interpolations when modeling anisotropic materials. In this letter, we focus on accurately implementing perfect electric conductors with planar interfaces, as well as 90° and 270° corners. Simulations are provided to demonstrate the overall improvements and also the second-order accuracy of the proposed methods. |
