NV Field

This documentation was written for releases up to 2018 and is being revised. Some dialogs have changed since. If something does not match what you see, write to mc@mcgrating.com.

This page is intended for Normal Vector Field visualization.
The structure calculation is completely independent from this page controls.

Layer Index defines the grating layer index.
Above this control the FFT grid size is indicated.
Graph Type control has two options:
- Interface displays in the FFT grid the NV Field at interfaces only.
- Full Field displays full NV Field in the FFT grid.
- NV Field component selects NV Field component to display.
The user may display in the FFT grid the original NV Field with smoothing or not (see page Options) or the NV Field image used in real calculation. The last depends on number of orders (General page) repeated in the Root-mean-square error at Interface panel. This panel presents average difference between the original and the image of three NV Field components. These values are calculated during the NV Field displaying. The NV Field values are significant only at interfaces. So, minimizing these errors by playing with smoothing parameters (see page Options) will increase the reliability of NV Field using.
