Abstract
We demonstrate that the left-handed materials (LHMs) with unity dendritic unit cells arrayed in disorder state present still passband and negative refractive. The resonance behavior of LHMs in disturbed periodic lattice, quasi-periodic lattice and random array are experimentally investigated. Employing amended retrieval method, the LHMs with disordered state exhibits a negative index of refraction. Basing on such LHMs lens, the subwavelength imaging experiment give a clearly point image with a full wave at half maximum width of 0.4 λ at 9.3 GHz. Similarly, the power field distribution of "N" shaped antenna is measured beyond the diffraction limit.
