In this study, metamaterial absorber structures that operate in the mid-wave infrared (MWIR) region are presented. The advantage of the design stems from the high absorptance in the region of interest and the ease of fabrication. Fabrication stage is facilitated by large in-plane geometric dimensions of the metamaterial pattern and small thickness of the full absorber geometry.

Electromagnetic Energy Harvesting By Using Tunable Metamaterial Absorbers Bakir, Mehmet; KARAASLAN, MUHARREM; Dincer, Furkan; Akgol, Oguzhan; ÜNAL, EMİN; DELİHACIOĞLU, KEMAL; Sabah, Cumali (2015-05-19) In this study, electromagnetic (EM) energy harvesting by using metamaterial absorber is numerically explained. Operation frequency is 2.40 GHz since it is the industrical scientific and medical (ISM) band. This band is especially chosen due to most of the customer electronic devices are working in this band. Split ring resonator that have two splits on it used in this study, chip resistors are placed on these splits for wireless energy transfer to the devices. 83.6% efficient electromagnetic energy harvesti...
A Solution to the Adhesion Problem of Oxide Thin Films on Zinc Selenide Optical Substrates Cosar, M. B.; Aydogdu, G. H.; Batman, H.; Ozhan, A. E. S. (2016-05-13) Zinc selenide optical substrates have high transparency within the 0.5- to 14.0-mu m wavelength range. This makes them an attractive candidate for multiband imaging applications in optical components. In order to minimize reflection loss in visible, near-infrared, and mid-infrared applications, zinc selenide lenses are coated with multi-layered oxide thin films by physical vapor deposition method or ion beam deposition. In this study, a four-layer anti-reflective filter at 1.064 gm and between 3.6 and 4.9 g...
Asymmetric transmission of linearly polarized electromagnetic waves using chiral metamaterials with constant chirality over a certain frequency band Akgöl, Oğuzhan; Dinçer, Furkan; Karaaslan, Muharrem; Ünal, Emin; Sabah, Cumali (World Scientific Pub Co Pte Lt, 2014-12-30) In this study, a dynamic chiral metamaterial (MTM) structure leading to an asymmetric electromagnetic (EM) wave transmission for linear polarization is presented. The structure is composed of square-shaped resonator with gaps on both sides of a dielectric substrate with a certain degree of rotation. The dynamic structure is adjustable via various parameters to fit any desired frequency ranges. Theoretical and experimental analysis of the proposed structure are conducted and given in detail. The suggested mo...
Dual-band high-frequency metamaterial absorber based on patch resonator for solar cell applications and its enhancement with graphene layers Ustunsoy, Mehmet Pasa; Sabah, Cumali (2016-12-05) In this paper, a dual-band high-frequency metamaterial absorber based on patch resonator is designed and analyzed for solar cells. In order to obtain a metamaterial absorber, metal-semiconductor-metal layers are combined. The results of the designed structure are shown in the infrared and visible ranges of solar spectrum. Structural parameters and dimensions of the device have a significant importance on the performance of the designed absorber. The simulations are carried out with full-wave electromagnetic...
The use of gold and silver nanoparticles for surface enhanced fluorescence (SEF) of Dyes Öztürk, Tacettin; Volkan, Mürvet; Department of Chemistry (2010) This study focuses on preparing surface enhanced fluorescence (SEF) substrates for use in the enhancement of the emission signal of rhodamine B and fluorescein dyes. Fluorescence spectroscopy has been widely utilized owing to its high sensitivity. SEF is a process where the interactions of fluorophores with the localized surface plasmons of metal nanoparticles results in fluorescence enhancement, increased photostability and rates of system radiative decay which leads to a decreased lifetime. One of the mos...
