modeexpansion - Script command – Ansys Optics

DGTD FEEM

Returns the mode expansion coefficients with respect to two FEEM solver results, or a FEEM solver result and a DGTD 2D frequency monitor result. The script command expects two structs according to the modeoverlap input.

Syntax	Description
out = modeexpansion(struct1, struct2);	struct1: struct name of the struct containing the fields E₁ and H₁ according to expand/ expand2 struct2: struct name of the struct containing the fields E₂ and H₂ according to expand/ expand2 out: mode expansion coefficients a, b, N, P as a struct (cf. expand,expand2)
out = modeexpansion(struct1, struct2, conjugated);	The optional bool argument is set to be true by default (cf. expand). If false, the unconjugated fields are used to calculate the mode expansion (cf. expand2).

Example

Using the two structs given in modeoverlap one can calculate the mode expansion coefficients as follows:

?modeexpansion(feem_struct, dgtd_struct);
?modeexpansion(feem_struct, dgtd_struct, false);

Note that bent waveguide FEEM calculations are not supported by this feature.
