3.1 Warnings

If you deal with warnings, the program won't stop, but it could be that it works with other parameters than the one you had in mind. Be happy, 'Errors' are worse.

• polarisation warning: You can only use TE or TM when calling set_polarisation()

• slab warning: Make sure al slabs have the same width. If put in a stack, the 'period' of the grating will be the width of the first slab

• section warning: Make sure all sections have the same height and width. In a stack, the grating will use the width and height of the first section.

• stack warning: The first and the last layer exist of only one material. If this isn't the case, the first material of the layer will be used.
