Experimental observation of cavity formation in composite metamaterials
(Optical Society of American (OSA), 2008)In this paper, we investigated one of the promising applications of left-handed metamaterials: composite metamaterial based cavities. Four different cavity structures operating in the microwave regime were constructed, and ... -
Graphene-enabled electrically switchable radar-absorbing surfaces
(Nature Publishing Group, 2015)Radar-absorbing materials are used in stealth technologies for concealment of an object from radar detection. Resistive and/or magnetic composite materials are used to reduce the backscattered microwave signals. Inability ... -
Surface plasmon based enhanced transmission of electromagnetic waves
(Bilkent University, 2004)Grating-coupling phenomena between surface plasmons and electromagnetic waves are studied in the microwave spectrum using metallic gratings. Transmission and reflection measurements were carried out to observe the transmitted ... -
Transmission enhancement through deep subwavelength apertures using connected split ring resonators
(Optical Society of American (OSA), 2010)We report astonishingly high transmission enhancement factors through a subwavelength aperture at microwave frequencies by placing connected split ring resonators in the vicinity of the aperture. We carried out numerical ...
