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.

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...

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 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....
Design and fabrication of a detector logarithmic video amplifier
Dinç, Mustafa Barış; Yıldırım, Nevzat; Department of Electrical and Electronics Engineering (2011)
In this thesis a single stage detector logarithmic video amplifier is designed with a dynamic range of 40dB in 2-6GHz frequency band. Since the detector logarithmic video amplifier (DLVA) is used to convert the power of the RF signals to video voltages in logarithmic scale, it can be regarded as a logarithmic converter instead of logarithmic amplifier. The design is composed of two main parts: The Schottky diode detector rectifies the incoming RF signal and produces a video voltage and the logarithmic ampli...
Design of a dual polarized low profile antenna for microwave brain imaging
Üçel, Kaan; Alatan, Lale; Department of Electrical and Electronics Engineering (2022-5-9)
In this thesis, a low profile, low cost, wide band (0.9-2GHz) dual linearly polarized printed dipole antenna is designed to be used in microwave brain imaging systems. Dual polarization feature offers superior data acquisition through polarization diversity for better image quality. Starting from a simple printed dipole, antenna structure is modified step by step to meet these design requirements. Since a conductive surface in close vicinity of the antenna affects antenna performance, in order to obtain uni...
