Panel-allocated defect SRRs effect in X-band LHMs

We experimentally investigated the defect ef- fects of LHMs when panel-allocated defects SRRs are intro- duced. By measuring the X-band transmission through metamaterial with different sizes and orientations panel- allocated defect SRRs, it was found that characters of reso- nant peak, including resonance frequency, magnitude and band pass, markedly change. And the panel-allocated defects in LHMs have more effect on electromagnetic behavior than that of dot and linear ones. It is thought that the existences of panel-allocated defects break the symmetry of perfect LHMs and result in a new electromagnetic resonance.
