Grating_trans
ComponentModel of a 1D rectangular transmission grating based on the theory developed in Schnopper et. al., Applied Optics, 1977. The grating lines are assumed to be vertical. Within each period a fraction gamma is the "open" fraction. (I.e. 1 is completely open). At present only absorption in the substrate (modelled by the thickness sdepth) is included. This component is currently undergoing validation.
Name | Unit | Description | Default |
fixed_delta | 0 | ||
xwidth | m | Width of the grating. Defines how many lines there are in total. | 1e-3 |
yheight | m | Height of the grating. | 1e-3 |
period | m | Distance between grating grooves. | 1e-6 |
gamma | Ratio between groove and period aka duty cycle. 1 means fully open. | 0.5 | |
zdepth | m | Depth of grooves. | 1e-6 |
sdepth | m | Thickness of substrate. The default is to have no substrate - i.e. rods. | 0 |
material | str | Data file containing the material from which the grating is made. | "Au.txt" |
substrate | str | Data file containing material data for the substrate. | "" |
