Theoretical and experimental investigations of easy made fishnet metamaterials at microwave frequencies

Abstract : In this work, we demonstrate theoretically and experimentally a left handed behaviour of a planar fishnet type metamaterial in the microwave regime. The fabrication process is very easy, unique and doesn’t involve optical lithography. The effective parameters were extracted using the S parameter retrieval method and show a perfect agreement between simulation and experiment. Using finite element method based simulations and W-band (75GHz – 110GHz) experiments, we obtained a negative index of refraction of -4 at 85GHz. The left handed materials discussed here represent a step towards the easy fabrication of metamaterials with a negative refractive index and paves the way for the active manipulation of millimeter wavelengths.
