Cavity resonances are observed in the transmission spectrum of a split ring resonator and composite metamaterials cavity structures. These cavity resonances are shown to exhibit high quality factors. Since the unit cells of metamaterials are much smaller than the operation wavelength, subwavelength localization is possible within these metamaterial cavity structures. In the present paper, we show that the electromagnetic field is localized into a region of λ/8, where λ is the cavity resonance wavelength.EnglishElectromagnetic fieldsPlasmonsCavity resonancesComposite metamaterialsDefect formationHigh quality factorsOperation wavelengthSplit ring resonatorSub-wavelength localizationTransmission spectrumsMetamaterialsConference Paper
