Compacted tunable split-ring resonators [PDF]
Applied Physics Letters, 2013 We propose tunable superconducting split-ring resonators (SRRs) employing nonlinear Josephson inductance. A fraction of SRR is replaced by Nb-AlOx-Nb Josephson tunnel junctions connected in parallel and forming a superconducting quantum interference device, whose inductance is sensitive to the external dc magnetic field. Due to the lumped nature of the

Spectral Imaging of Individual Split-Ring Resonators [PDF]
Physical Review Letters, 2010 We report on spectral imaging within individual silver split-ring resonators (SRRs) operating in the near infrared-visible range. We classified the optical eigenmodes from the measurement of their energies and nanometer scale spatial distributions. They are plasmonic standing waves that show great similarities with that of nanoantennas.

Double Split-Ring Resonator for Dielectric Constant Measurement of Solids and Liquids
Journal of Electromagnetic Engineering and Science, 2022 This study proposes a 2.45-GHz double split-ring resonator for measuring the dielectric constant in both solids and liquids. Two concentric rectangular rings with asymmetric splits are used in the proposed resonator to achieve a high-quality factor for ...

Multiresonant Split Ring Resonator with Meandered Strips [PDF]
physica status solidi (a), 2020 A multiresonant split ring resonator (SRR) composed of two circular‐shaped meandered strips is presented. Resonances are first analyzed by means of eigenmodes computation and field mapping. It is shown that a resonance can emerge from a standing wave taking place in each slot produced by a meandered strip.

Design of a dual linear polarization antenna using split ring resonators at X-band [PDF]
Advances in Radio Science, 2017 Dual linear polarization microstrip antenna configurations are very suitable for high-performance satellites, wireless communication and radar applications. This paper presents a new method to improve the co-cross polarization discrimination (XPD) for

Dynamically tunable terahertz metamaterial sensor based on metal–graphene hybrid structural unit
AIP Advances, 2022 By verifying the electromagnetic response characteristics of graphene in the low terahertz (THz) band, a terahertz metamaterial sensor is proposed. The unit cell of the metamaterial sensor is a split ring resonator nested square ring resonator. The split

Miniaturised self-resonant split-ring resonator antenna [PDF]
Electronics Letters, 2009 A self-resonant miniaturised antenna composed of a broadside-coupled split ring resonator (SRR) and an excitation arc-shaped monopole is presented. The size of the antenna and its resonance frequency is essentially defined by the SRR dimensions and geometry, while the input resistance at the resonance is governed by the arc length of the monopole ...

Proceedings of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2010 We obtain band diagrams for a two-dimensional periodic structure consisting of an infinite square array of infinitely thin concentric circles (split rings) with narrow gaps. Our approach exploits the narrowness of the gaps and yields algebraic equations relating the frequency to the Bloch wavenumber and geometric properties of the array.

Nonlinear properties of split-ring resonators
Optics Express, 2008 In this letter, the properties of split-ring resonators (SRRs) loaded with high-Q capacitors and nonlinear varactors are theoretically analyzed and experimentally measured. We demonstrate that the resonance frequency $f_m$ of the nonlinear SRRs can be tuned by increasing the incident power. $f_m$ moves to lower and higher frequencies for the SRR loaded
