Enhanced transmission of microwave radiation in one-dimensional metallic gratings with subwavelength aperture
(American Institute of Physics, 2004)We report a theoretical and experimental demonstration of enhanced microwave transmission through subwavelength apertures in metallic structures with double-sided gratings. Three different types of aluminum gratings ... -
Experimental demonstration of transmission enhancement through subwavelength apertures at microwave frequencies
(Bilkent University, 2012)Metamaterials are artificial materials with novel electromagnetic characteristics. They are used in many applications including imaging, super lenses, cloaking, transmission enhancement, beaming and recently in nano ... -
Extracting power from sub-wavelength apertures by using electrically small resonators: Phenomenology, modeling, and applications
(2012)In this contribution, we review our recent work on the extraction of the electromagnetic power from electrically small apertures by using metamaterial-inspired resonators. First, we present an antenna interpretation of the ... -
Near-field light localization using subwavelength apertures incorporated with metamaterials
(Elsevier, 2012-03-12)We report strong near-field electromagnetic localization by using subwavelength apertures and metamaterials that operate at microwave frequencies. We designed split ring resonators with distinct configurations in order to ... -
Resonant artificial structures to achieve extraordinary transmission at microwaves
(2010)In this contribution, the role of artificial resonant structures in increasing the transmission through sub-wavelength apertures is discussed. Those devices are capable to enhance the aperture equivalent electric and ... -
Surface wave splitter based on metallic gratings with sub-wavelength aperture
(Optical Society of American (OSA), 2008)We investigated the splitting of surface electromagnetic waves trapped at the output surface of a one-dimensional metallic grating structure. The output gratings of the structure asymmetrically such that the output surfaces ... -
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 ...
