I wanna add a DC E-field to the unit SRR cell, the vector of incident wave as the FIGURE(1).
I use the PEC and PMC to define the periodic boundry on x-z plane, wave ports applied on right and left facets, now, how can I add a uniform DC E-field whose direction is parallel to z-axis ???
I inter a rectangle plane with voltage excitation along -z direction and excitation wave port on both side of right and left face, but I still can not get the uniform DC E-field.
