Genetic algorithm synthesis of planar zero index metamaterials for the infrared with application to electromagnetic cloaking

A planar metamaterial structure using a single Ag FSS screen sandwiched between layers of polyimide was proposed that is straightforward to fabricate. This structure was optimized by a GA to have a low/zero index of refraction with high transmission in the far-IR. Measured dielectric and metallic properties incorporation into the model provide confidence that the PMM predictions are accurate. Fabrication constraints in the GA ensured that the design result can be fabricated. Experimental efforts are currently underway to characterize this design for the predicted ZIM properties.
