Metagratings, which are usually composed of nanopillars with spatially varying parameters, are shown to have superior performance in comparison to traditional gratings. Such gratings can be set up in VirtualLab Fusion with the help of the pillar medium and, in this example, we show how to properly configure the metagrating setups. That includes the settings of media, materials, the pillar geometry, and the spatial distribution of the pillars. Additional hint is given on the setting of number of spatial frequencies is also given.
