Terahertz applications of frequency selective surfaces: analysis, design, fabrication and testing

In this paper, metallodielectric IR FSS filters were synthesized using fractal and GA techniques with fabrication constraints. Measured results show excellent agreement with PMM simulation. The synthesis of DFSS for near-IR filter applications was performed using a GA. The advantages of DFSS include low loss at visible wavelengths and polarization independent filter responses. Designs for low loss IR NIMs based on FSS were also discussed. Future work includes fabricating FSS and DFSS filters that operate at near-IR and visible wavelengths
