Improved Split-Ring Resonator for Microfluidic Sensing [PDF]
IEEE Transactions on Microwave Theory and Techniques, 2014 We present a method of making low-loss split-ring resonators (SRRs) for microfluidic sensing at microwave frequencies using silver-coated copper wire. We show that a simple geometric modification and the use of square cross-section wire give greater electric field confinement in the capacitive region of the resonant sensor.

Tunable split-ring resonators for nonlinear negative-index metamaterials [PDF]
, 2006 We study experimentally the dynamic tunability and self-induced nonlinearity of split-ring resonators incorporating variable capacitance diodes. We demonstrate that the eigenfrequencies of the resonators can be tuned over a wide frequency range, and ...

On the resonances and polarizabilities of split ring resonators
Journal of Applied Physics, 2005 In this paper, the behavior at resonance of split ring resonators (SRRs) and other related topologies, such as the nonbianisotropic SRR and the broadside-coupled SRR, are studied. It is shown that these structures exhibit a fundamental resonant mode (the quasistatic resonance) and other higher-order modes which are related to dynamic processes.

Miniaturized planar split-ring resonator antenna [PDF]
2009 IEEE Antennas and Propagation Society International Symposium, 2009 A miniaturized planar antenna based on a broadside-coupled split ring resonator excited by an arc-shaped dipole is presented. The excitation dipole acts as a small tuning capacitor in series with a parallel RLC circuit represented by the SRR. The antenna resonance frequency and dimensions a essentially determined by the SRR, while by varying the dipole

On the reinterpretation of resonances in split-ring-resonators at normal incidence
Optics Express, 2006 We numerically study the spectral response of 'U'-shaped split-ring-resonators at normal incidence with respect to the resonator plane. Based on the evaluation of the near-field patterns of the resonances and their geometry-dependent spectral positions, we obtain a comprehensive and consistent picture of their origin.

Coupling enhancement of split ring resonators on graphene [PDF]
Carbon, 2014 Metallic split ring resonator (SRR) structures are used in nanophotonics applications in order to localize and enhance incident electromagnetic field. Electrically controllable sheet carrier concentration of graphene provides a platform where the resonance of the SRRs fabricated on graphene can be tuned.

Resonance hybridization in double split-ring resonator metamaterials
Optics Express, 2007 We introduce a plasmon hybridization picture to understand the optical properties of double split-ring resonator metamaterials. The analysis is based on the calculated reflectance spectra from a finite-integration time-domain algorithm. Field distributions of the double split-ring resonators at the resonant frequencies confirm the results from the ...

Apex-angle-dependent resonances in triangular split-ring resonators [PDF]
Applied Physics A, 2016 Along with other frequency selective structures [1] (circles and squares), triangular split-ring resonators (TSRRs) only allow frequencies near the center resonant frequency to propagate. Further, TSRRs are attractive due to their small surface area [2], comparatively, and large quality factors (Q) factors as previously investigated by Gay-Balmaz, et ...
