“…[6][7][8][9] Although the method allows for scattering analysis from aperiodic and periodic structures comprised of complex unit cells, a much simplified version is used for the periodic circular aperture array in this paper. It consists of a field expansion in each of the regions (air and hole) in its own eigenmodes (Floquet and waveguide modes) and then matching them by imposing boundary conditions.…”

In a similar manner to the frequency selective surfaces commonly used in the microwave regime, we have designed antireflective surfaces in the mid-infrared (2-5µm). Translation of microwave designs to the infrared is not trivial for several reasons. Properties of applicable IR materials are significantly different than their microwave counterparts. Additionally, the required feature sizes need a completely different fabrication methodology. Our surfaces are metallic, yet have a high-transmission angular and frequency passband. We take advantage of photonplasmon interaction to maximize transmission through holes in the metal surface. Simulations have been completed using both rigorous coupled wave analysis and method of moments codes. The design process has followed a path that insures that we are able to fabricate the designed structures considering cases of normal and off-angle incidence. We designed our surfaces to be compatible with shapes that we will etch in silicon and then coat in gold: this process allows the greatest flexibility in etching shapes for vias while maintaining a metallic layer for plasmon propagation on the surface. We anticipate over 90% transmission in the infrared passband. Our design methodology would also be applicable to the 8-12µm band.

“…Thin screen FSS are lightweight, small in volume and easy to fabricate with the conventional printed circuit technology. Thick screen FSS [25][26] are made of array elements with electrically larger thickness, and are mostly apertures used for high-pass applications. Compared with thin screen FSS, the advantage of thick screen FSS is that closely spaced frequency bands, shaper frequency roll-off and wider pass-band bandwidths.…”
