Abstract :
Here we present numerical and experimental results of a zoned fishnet metamaterial lens with dual-band response. Good performance is demonstrated at frequencies 54 GHz and 55.5 GHz at which the fishnet metamaterial behaves as a medium with refractive indexes n1 = -0.78 and n2 = -0.43, respectively. Experimental focal lengths are FL1=8.4λ1 and FL2=9.4λ2. The dual-band response of zoned fishnet metamaterial lens shows potential for application in non-mechanical zoom millimeter-wave imaging system.
