Photonic magnetic metamaterial basics
(Elsevier, 2010-07-21) Alici, K. B.; Serebryannikov, A. E.; Özbay, Ekmel
In the present study, we provide a detailed analysis for the study of photonic metamaterials. We demonstrate the polarization and orientation dependent transmission response of split ring resonators at the infrared and visible band. We provided optical measurements only for one case, in which electric component of the incident field was coupled to planar split ring resonator array. We consecutively studied (i) frequency tuning, (ii) effect of resonator density, (iii) shifting magnetic resonance frequency by changing the resonator shape, and (iv) effect of metal loss and plasma frequency. The study provides an overlook for the candidate applications such as the enhancement of power passing through an electrically small hole, negative index metamaterials and optical metamaterial absorbers.

Photonic metamaterial absorber designs for infrared solar-cell applications
(SPIE, 2010) Alıcı, Kamil Boratay; Özbay, Ekmel
We propose a metamaterial based absorber design that operates at the infrared regime. The absorption peak was 83.6%. We can incorporate solar-cell layers inside the metamaterial absorber in order to significantly increase solar-cell efficiency. © 2010 SPIE.

Photonic metamaterials: science meets magic
(IEEE, 2010-04) Özbay, Ekmel
The word magic is usually associated with movies, fiction, children stories, etc., but seldom with the natural sciences. Recent advances in metamaterials have changed this notion, in which we can now speak of almost magical properties that scientists could only dream about a decade ago. In this paper, we review some of the recent almost magical progress in the field of photonic metamaterials.

Science meets magic: photonic metamaterials
(Society of Photo-Optical Instrumentation Engineers, 2012-05) Özbay, Ekmel
The word "magic" is usually associated with movies, fiction, children stories, etc. but seldom with the natural sciences. Recent advances in metamaterials have changed this notion, in which we can now speak of "almost magical" properties that scientists could only dream about only a decade ago. In this article, we review some of the recent "almost magical" progress in the field of meta-materials. © 2012 Copyright Society of Photo-Optical Instrumentation Engineers (SPIE).
