For a triangular shape, we need 3 points (x1,y1), (x2,y2), and (x3,y3) to define the triangular shape. Then the refractive index and the absorption coefficient is put in the simulation.

Example

Type.1~4 are triangle, circle, ellipse and rectangle.

If the parameters are not show in the figure, you should set those parameters as 0.

Type5~8 are sine shape period structure.

Type.5 and 6 can be determined by this expression:

f_6<y<f_1sinf_2x+f_3;

f_4<x<f_5

Type.7 and 8 can be determined by this expression:

f_6<x<f_1sinf_2y+f_3;

f_4<y<f_5
