Metamaterial Sensor Applications Based on Broadside Coupled SRR and V Shaped Resonator Structures

Sayan, Gönül
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.


Metamaterial Absorber Based Multifunctional Sensors
Sabah, Cumali (The Electrochemical Society, 2016-01-01)
In this paper, several important applications of a metamaterial absorber (MA) based sensors such as temperature, pressure, moisture, and density are presented. Since the sensing ability mostly considers the resonance frequency, the frequency range where the resonance shifts occur linearly or non-linearly depending on the temperature, pressure, moisture, and density changes is selected carefully. The model is composed of X shaped resonators (XSR), dielectric substrate, the sensing layer, dielectric substrate...
Multifunctional metamaterial sensor applications based on chiral nihility
In this paper, chiral nihility based pressure, density, temperature and moisture content metamaterial sensor applications are investigated in detail. A "chiral nihility'' medium in which both the permittivity and the permeability tend to zero is investigated. Gammadion shaped resonators particularly designed for chiral nihility are introduced. Bandwidths and signal strengths show admissible results. Simulation and experimental results prove that chiral nihility occurred at the resonance frequencies when med...
Current transport mechanisms in low resistive CdS thin films
Günal, İbrahim; Parlak, Mehmet (Springer Science and Business Media LLC, 1997-02-01)
The current transport mechanisms in polycrystalline CdS thin films have been studied as a function of temperature over the temperature range 20-230 K. Conductivity data for the high temperature region has been analysed using Seto's model of thermionic emission. At intermediate temperatures it was found that thermionic emission and tunnelling of carriers through the potential barrier both contribute to the conductivity. Below 100 K Mott's hopping process appears to be the predominant conduction mechanism.
Optoelectronic and electrical properties of TlGaS2 single crystal
Qasrawi, AF; Hasanlı, Nızamı (Wiley, 2005-10-01)
The optoelectronic and electrical properties of TIGaS2 single crystals have been investigated by means of room temperature transmittance and reflectance spectral analysis, Hall coefficient, dark electrical resistivity and photocurrent measurements in the temperature range of 200-350 K. The optical data have revealed an indirect and direct allowed transition band gaps of 2.45 and 2.51 eV, an oscillator and dispersion energy of 5.04 and 26.45 eV, respectively, a static dielectric constant of 6.25 and static r...
Thermally stimulated currents in layered Ga4SeS3 semiconductor
Aytekin, S; Yuksek, NS; Goktepe, M; Hasanlı, Nızamı; Aydinli, A (Wiley, 2004-10-01)
Thermally stimulated current (TSC) measurements are carried out on nominally undoped Ga4SeS3 layered semiconductor samples with the cur-rent flowing along the c-axis in the temperature range of 10 to 150 K. The results are analyzed according to various methods, such as curve fitting, initial rise and Chen's methods, which seem to be in good agreement with each other. Experimental evidence is found for the presence of three trapping centers in Ga4SeS3 with activation energies of 70, 210 and 357 meV. The calc...
