Material Mixture Definitions and Index Bounds
Ease into the design of gradient index lenses with this GEMSIF file for a Luneberg lens!
Explore Metasurfaces
Ideal metasurface definitions are supported on all lens objects in reTORT. Metasurfaces are modeled in a similar way to a diffraction grating but allow for arbitrary wavelength dependence. Start with this GEMSIF file to explore metasurfaces!
Hybridization Metasurface Demonstration
Still in development but take a peak at the future of interoperability among the GEMSIF suite of solvers with this example of hybridization. Just download this GEMSIF file and, for reference, you can download this explanatory PDF!
