In this work, we demonstrate theoretically and experimentally a left handed behaviour of a planar fishnet type metamaterial in the microwave regime. The fabrication procedure based on printed circuit board technology and mechanical micromachining technique is easy, unique and doesn't involve optical lithography. The effective parameters have been extracted using the S parameter retrieval method and show a very good agreement between simulation and experiment. Using finite-element method based simulations and W-band (75 GHz-110 GHz) experiments. We measured a negative index of refraction of −4 at 85 GHz. The demonstrated left handed materials represent a step towards the easy fabrication of metamaterials with a negative refractive index that open a new path for the active manipulation of millimetre wavelengths.< Réduire
