Dear All, I am writing to you all for help. These days i have been simulating a 3-D model of a periodic structure with oblique incidenting circular polarized light. But I have encountered some problems that have been solved for a long time. I want to define a circular polarized light with an angle of theta between the k and z axes, and k is on the z-x plane, that is the polar angle theta is not equal to 0°，the azimuthal angle phi is equal to 0°. My settings are as follows：I chose "periodic" in type of port and I defined the polarization of circular polarized light at both input and output port : cos (theta) in x direction, a* i in y direction, and -sin(theta) in z direction. Then, i chose "floquent periodicity" in x and y direction in periodic condition. And I chose "from periodic port" in k-vector for floquent periodicity. However, the charge map derived from the calculation results is not continuous on the right and left side of the structure in x direction. I don't know if my periodic conditions are wrong. If wrong, how should I revise. Any reply would be greatly appreciated. Sincerely yours, Zhimin Jing
