Miniaturized negative permeability materials

Cataloged from PDF version of article. Experimental and numerical studies of mu-negative (MNG) materials such as multisplit ring resonators (MSRRs) and spiral resonators (SRs) are presented. The resonance frequency of the structures is determined by the transmission measurements and minimum electrical size of lambda(0)/17 for the MSRRs and of lambda(0)/82 for the SRs observed. These MNG materials can be easily produced by the well developed printed circuit board and optical lithography techniques. They are promising elements for the development of high resolution metamaterial lenses and electrically small antennas. (c) 2007 American Institute of Physics.
