A new near-perfect metamaterial absorber (MA) consisting of a square resonator with gaps and cross-wire strips is presented for the sub-terahertz frequency range. A narrow-band response of the proposed MA provides near-perfect absorption (absorbance of 99.23%) at 0.6 THz. In addition, numerical simulations show that the suggested MA could achieve very high absorption over a wide range of angles of incidence at least for transverse magnetic (TM) waves. As a result, the suggested model can be used for numerous potential application areas in defense systems, communications, stealth technologies, and so on.

Design and analysis of perfect metamaterial absorber in GHz and THz frequencies Dincer, Furkan; KARAASLAN, MUHARREM; Sabah, Cumali (2015-12-12) The new perfect metamaterial absorber (MA) based on square resonator with gap configuration is numerically (for GHz and THz frequency regime) and experimentally (for GHz frequency regime) presented and investigated. The proposed MA has a simple configuration which introduces flexibility to adjust its metamaterial properties and easily rescale the structure for other frequency regimes. In addition, polarization and incident angle independencies of the proposed model are analyzed for the THz frequency regime....
Investigation of microwave metamaterial based on H-shaped resonator in a waveguide configuration and its sensor and absorber applications Sabah, Cumali; Taygur, Mehmet Mert; ZORAL, EMİNE YEŞİM (2015-04-13) A microwave metamaterial (MTM) based on H-shaped resonator in a waveguide configuration is introduced and investigated both numerically and experimentally for X-band frequencies. The proposed model is designed and fabricated on both sides of the substrate and exhibits strong magnetic resonance at around 10.5GHz. Additionally, it has very simple design which improves and simplifies the fabrication process. Besides, only one single slab is used in the simulation and experiment which provides a reduction in th...
Design and realization of broadband instantaneous frequency discriminator Pamuk, Gökhan; Yıldırım, Nevzat; Department of Electrical and Electronics Engineering (2010) n this thesis, RF sections of a multi tier instantaneous frequency measurement (IFM) receiver which can operate in 2 – 18 GHz frequency band is designed, simulated and partially realized. The designed structure uses one coarse tier, three medium tiers and one fine tier for frequency discrimination. A novel reflective phase shifting technique is developed which enables the design of very wideband phase shifters using stepped cascaded transmission lines. Compared to the classical phase shifters using coupled ...
Design, Implementation, and Operation of a New C-Type 2nd Harmonic Filter for Electric Arc and Ladle Furnaces Gercek, Cem Ozgur; Ermiş, Muammer; Ertas, Arif; Kose, Kemal Nadir; Unsar, Ozgur (2011-07-01) In this paper, the transient overvoltage suppression capability and harmonic filtering performance of C-type 2nd harmonic filters (HFs) are optimized by using two-stage damping resistors; one is permanently connected to the filter circuit, while the other one is switched on by back-to-back connected thyristors during furnace transformer and HF energization periods. However, in conventional C-type 2nd HFs, there is only one damping resistor, which is permanently connected to the filter circuit. In convention...
Effects of Array Dimensions on the Resonance Characteristics of SRR Type Metamaterial Arrays with Small Sizes: Simulations and Experiments Ekmekci, E.; Topalli, K.; Akın, Tayfun; Sayan, Gönül (2009-08-21) It has been discussed in various studies that two dimensional periodical arrays of SRRs with large array sizes have wider stop bandwidths and lower transmission magnitudes around their resonance frequencies as compared to the single SRR unit cell. In this paper, effects of array dimensions on the transmission characteristics of SRR arrays are investigated in more detail especially for small sized arrays in a comparative manner. For this purpose, various SRR arrays with small array sizes are fabricated and t...
