Hi all, is there a way to excite a fundamental mode wave from a patterned layer? I have tried a simple layer
Layer *L1 = Simulation_AddLayer(S); Layer_Init(L1, "above", 0.5, "air", NULL); Simulation_AddLayerPatternCircle(S, L1, 1, center, 0.5 * w_x);
Excite it using
int exg[2] = {1, 1}; double ex[2] = {1.0, 0.0}; Simulation_MakeExcitationExterior(S, 1, exg, ex);
However exciting from it will yield strange negative input flux:
layer forw_r back_r forw_i back_i
L1 -0.4756 30.9501 1.11022e-15 -1.11022e-15
L3 30.4744 0 0 0
