In this study, metamaterial inspired, electrically small, single band antennas with steerable radiation patterns and high radiation efficiencies are proposed. Three different antenna structures having their maximum directivities in the vertical (Antenna A), diagonal (Antenna B) and horizontal (Antenna C) directions are presented and their simulated performance characteristics are reported. These antennas, which consist of a coax-fed printed monopole and a capacitively loaded loop (CLL) as a near-field resonant parasitic element, radiate as magnetic dipoles at each of their resonance frequencies, which are defined mainly by the size of the CLL element and its gap. The direction of the maximum radiation is controlled by the position of the monopole and the CLL gap. These antennas are designed to operate at the GSM frequencies (1.93-1.99GHz). For each of these antenna designs, ka is smaller than 0.58 at its operating frequency. The radiation efficiencies of Antenna A, B and C are equal to 0.89, 0.91 and 0.81 respectively.

Tunable perfect metamaterial absorber design using the golden ratio and energy harvesting and sensor applications ÜNAL, EMİN; Dincer, Furkan; TETİK, ERKAN; KARAASLAN, MUHARREM; Bakir, Mehmet; Sabah, Cumali (2015-12-01) We present the design, characterization, theoretical and experimental verification of a tunable perfect metamaterial absorber (MA) based electromagnetic (EM) energy harvesting and sensor application. We have used the golden ratio while determining the dimensions allowing a simple configuration and an easy fabrication for the proposed structure. We have examined and analyzed the perfect absorption (both numerically and experimentally) and EM energy harvesting (numerically) behaviors of the proposed structure...
Metamaterial based wideband infrared absorbers Üstün, Kadir; Sayan, Gönül; Department of Electrical and Electronics Engineering (2017) In this thesis, design and simulation of wideband metamaterial absorbers are investigated in the long wave infrared (LWIR) and the mid-wave infrared (MWIR) bands of the electromagnetic spectrum. Use of LWIR and MWIR bands in absorber design is especially important for critical applications including the design of thermal cameras and thermal emitters. Integration of metamaterial topologies into the absorber structures provides flexibilities in design to enhance the operation efficiency of these devices by in...
Metamaterial Sensor Applications Based on Broadside Coupled SRR and V Shaped Resonator Structures EKMEKÇİ, EVREN; Sayan, Gönül (2011-07-08) In this study, the use of broadside-coupled SRR (BC-SRR) metamaterial topology is suggested for pressure, temperature, humidity and concentration sensor applications. Also, the use of V-shaped resonator topology is suggested for pressure sensor application. The feasibility of such sensors are demonstrated by numerical simulations for microwave region under magnetic excitation.
Thin Wideband Infrared Metamaterial Absorber with Coplanar Metallic Patches of Different Sizes Ustun, K.; Sayan, Gönül (2016-01-01) Infrared absorber concept is a vibrant research topic because of the importance of real world applications such as infrared detectors, thermal coolers and energy harvesters. In this paper, we propose and numerically analyze thin metamaterial structures designed to operate in Long Wave Infrared Region, one of the regions that atmosphere shows transparent behavior. It is demonstrated that one of the proposed structures attains absorptance values higher than 80 percent in the wavelength region from 8.14 ium to...
Photonic Crystal and Plasmonic Silicon-Based Light Sources Makarova, Maria; Gong, Yiyang; Cheng, Szu-Lin; Nishi, Yoshio; Yerci, Selçuk; Li, Rui; Dal Negro, Luca; Vuckovic, Jelena (2010-01-01) Efficient silicon (Si)-compatible emitters can realize inexpensive light sources for a variety of applications. In this paper, we study both photonic crystal (PC) and plasmonic nanocavities that enhance the emission of Si-compatible materials. In particular, we examine the coupling of silicon nanocrystals (Si-NCs) to silicon nitride PC cavities and Si-NCs in silicon dioxide to plasmonic gratings, both for enhancement of emission in the visible wavelengths. In addition, we also observe the enhancement of the...
