Advanced Materials Interfaces, EarlyView.BioEISense is a microfluidic device with integrated impedance sensors, for real‐time, label‐free monitoring of S. aureus biofilms. In this study, the biofilm culture conditions were optimized to support sensitive and reproducible detection of biofilm formation and eradication under dynamic flow‐through conditions. The system was also validated for both

Linear birefringence in split-ring resonators
Optics Letters, 2012We study polarization-dependent transmission of light through arrays of single-slit split-ring resonator (SSRR) based systems at normal incidence using finite integration time domain (FITD) and finite element methods (FEM). It is found that a conventional planar array of SSRRs acts as an effective optical wave plate at certain polarizations of incident

Far-Infrared Resonance in Split Ring Resonators
Japanese Journal of Applied Physics, 2004We experimentally investigated the resonance effect of planar metallic split ring resonators (SRRs) in the far-infrared region (FIR) (~10.6 µm). Experimental results indicated that they exhibit resonance around 10.6 µm, implying negative permeability in the FIR region. Furthermore, the ratio of effective dimensions of the SRR cell and the wavelength of

Spinning a split ring resonator with microwaves
Applied Physics Letters, 2023The aim of this study is to spin a Split Ring Resonator (SRR) with microwaves. Analytical and numerical studies show that an SRR can be spun when it is excited at its resonance frequency by a circularly polarized electromagnetic wave. Experimentally, using a cylindrical waveguide, at 2.45 GHz and for 150 W, a 15 mm-diameter SRR was rotated with an ...

Plasmonic resonances in hexagonal split-ring resonator
2017 International Conference on Electrical, Computer and Communication Engineering (ECCE), 2017A nanoscale resonator is designed using a hexagonal split ring inside two metal-insulator-metal (MIM) waveguides. The split angle defined by the angular position of the split referring to the axis of the MIM waveguide is varied and thus the transmission properties as well as different plasmonic resonance modes have been investigated by numerical ...

Improved shield design for split-ring resonator
2015 Third International Conference on Technological Advances in Electrical, Electronics and Computer Engineering (TAEECE), 2015Shield or cavity around split-ring resonators is used for enhancing its output performance. Shield parameters which influence resonator performance include dimensions, material, electrical and mechanical properties. Performance is generally measured in terms of quality factor and resonant frequency.

ANN based optimization of resonating frequency of split ring resonator
2014 IEEE Symposium on Computational Intelligence for Communication Systems and Networks (CIComms), 2014It has been found that resonating frequency of split ring resonator depends on its physical dimension of the split structure such as width, gap and radius. The best possible combinations of all such physical parameters provide the proper resonating frequency over which the metamaterial property of the structure can be obtained.

A novel millimeter wave super lens using split-ring resonator and complementary split-ring resonator
2009 34th International Conference on Infrared, Millimeter, and Terahertz Waves, 2009We report a millimeter wave super lens based on the left-handed metamaterial using split-ring resonator (SRR) and complementary SRR (CSRR). The millimeter wave cannot propagate far away due to short wavelength. Therefore, the system for THz or millimeter wave band demands the lens to obtain strong focused signal from weak waves caused by scattering in ...

11th International Symposium on Antenna Technology and Applied Electromagnetics [ANTEM 2005], 2005
The study that is done in this paper compares the physical phenomena observed when placing a 50Ω microstrip line on respectively a periodic lattice of SRRs and a SSRRs defected ground plane. In both cases, a band-stop phenomenon is observed, but the coupling with the microstrip line is completely different.

Microstrip line periodically loaded with split-ring resonators (SRRs) and complementary split-ring resonators (CSRRs) is designed. By utilizing the CSRRs/gaps and SRRs/inductances combinations, two passbands are observed. Because of the negative permeability offered by SRRs and series capacitances, the negative permittivity offered by CSRRs and shunt ...
