Parameters of a Grating Surface

Vector

You must set orthogonal direction to grating lines.

Note: The vector defines the orthogonal direction to grating lines. It is absolutely necessary the vector is located in the surface plane, the latter defined as being the grating.

Warning: In simulation it is better that the light incidence plane is orthogonal to grating lines (co-linear to the file vector). This relates to the standard usage of a grating.

Note: Absorption represents an one hundred percent complement of the total amount of the first order transmission, specular transmission and specular reflection percentages. %A = 100% - %Rs -%Ts - %T1

Rs(%)

You must set reflection in specular direction in percent.

Ts(%)

You must set transmission in specular direction in percent.

T01(%)

You must set transmission for order 1 in percent.

A01(°)

You must set angle for order 1 in degree.
