This study investigates the sensing applications of metamaterial (MTM) structures in the terahertz (THz) region and is based on a broadside-coupled diamond and square ring resonator (DSRR) structures. The resonators are designed and simulated as sensors in detail. Compared with single-sided sensors, the sensing capability of double-sided sensors provide an enhancement with respect to the sensitivity. To analyze the structure as sensor, the changes in the transmission resonance are investigated as a function of the permittivity and thickness of overlayer for the single- and double-sided MTM. The results demonstrate that this design can provide good sensitivity when sensing the chemical or biological agents that are resonant in the terahertz region of the electromagnetic spectrum. These types of designs can be employed in the many sensing applications that are of interest in the THz region.

Multi-Point Single-Antenna Sensing Enabled by Wireless Nested Split-Ring Resonator Sensors Ozbey, Burak; ERTÜRK, VAKUR BEHÇET; Kurç, Özgür; ALTINTAŞ, AYHAN; DEMİR, Hilmi Volkan (2016-11-01) In this paper, simultaneous multi-point wireless sensing is proposed and demonstrated via multiple sensors in nested split-ring resonator (NSRR) geometry coupled to a single illuminator antenna. In this passive multi-point sensing system, each probe in the sensor array is assigned a non-overlapping spectral interval for frequency shift in response to local mechanical loading around a unique operating resonance frequency in the band of the antenna. Here, it is shown that the antenna is capable of capturing t...
3D scanning Hall probe microscopy with 700 nm resolution DEDE, MUNIR; AKRAM, RİZWAN; Oral, Ahmet (2016-10-31) In this report, we present a three dimensional (3D) imaging of magnetic field vector (B) over right arrow (x,y,z) emanating from the magnetic material surfaces using a scanning Hall probe microscopy (3D-SHPM) down to a 700 nm spatial resolution. The Hall probe is used to measure B-z(x,y) on the specimen surface at different heights with the step size of Delta z = 250 nm, as we move away from the surface in z direction, until the field decays to zero. These set of images are then used to get partial derivati...
Flexible chiral metamaterials with dynamically optical activity and high negative refractive index Dincer, Furkan; KARAASLAN, MUHARREM; ÜNAL, EMİN; Akgol, Oguzhan; Sabah, Cumali (2015-07-10) We demonstrate numerically and experimentally chiral metamaterials (MTMs) based on gammadion-bilayer cross-wires that uniaxially create giant optical activity and tunable circular dichroism as a result of the dynamic design. In addition, the suggested structure gives high negative refractive index due to the large chirality in order to obtain an efficient polarization converter. We also present a numerical analysis in order to show the additional features of the proposed chiral MTM in detail. Therefore, a M...
Microfluidic and Fuel Adulteration Sensing by Using Chiral Metamaterial Sensor BAKIR, MEHMET; KARAASLAN, MUHARREM; Unal, Emin; Karadag, Faruk; Alkurt, Fatih Ozkan; ALTINTAŞ, OLCAY; Dalgac, Sekip; Sabah, Cumali (The Electrochemical Society, 2018-08-08) In this study, Chiral Metamaterial Sensor (CMS), which is designed by utilizing a Split Ring Resonators (SRR) has been employed to reveal the two different types of sensor applications by experimentally and numerically. These applications include purity demonstration of methanol, ethanol and isopropyl alcohol (IPA) and fuel adulteration applications for petrol. All of the validations have been realized by measuring the complex permittivity values and reflection coefficients by using a vector network analyze...
Simulations for a novel magnetic resonator with V-shaped structures Ekmekci, Evren; Sayan, Gönül (2007-01-01) It is demonstrated in this paper that a novel structure which consists of V-shaped conducting strips may exhibit magnetic resonance effect similar to the split ring resonator structures. The simulations have been done using Ansoft HFSS v9.2. By applying a time varying electric field to the V-shaped structure, the location of the resulting resonant frequency has been determined and furthermore, the dependency of resonance frequency on arm width, arm angle, and dielectric thickness have been investigated.
