Realizing PEC boundary conditions on Lebedev grid

The Lebedev method is a collocated scheme which makes it more suitable for modelling anisotropic materials compared to Yee method as it removes the need for interpolation since all the field components exist at one location. In this work, we accurately realize planar perfect electric conductors (PEC) and also PEC corners on Lebedev grid. To show the accuracy of the proposed method, a rectangular resonator filled with anisotropic material will be simulated, and the results will be compared with the previous method and HFSS.
