Description
Summary:Plasmonic metamaterial design with cut-wire (CW) and Labyrinth resonator (LR) which respectively exhibit effective negative permittivity and effective negative permeability below plasma frequency has been carried out at Ka band (26.5-40 GHz). Analytical model equations for realization of effective negative permittivity over desired frequency range with CW structure have been derived. These model equations for CW in conjunction with the analytical model equations for effective negative permeability realizable with LR has been used to design Ka-band CW-LR type negative refractive index metamaterial. Also the design of metamaterial with conventional thin-wire (TW) and LR has been included. Performance characteristics of the resonant-resonant type (CW-LR) and the nonresonant-resonant type (TW-LR) metamaterial thus investigated has been compared from designer's point of view.
