Split Ring Resonators and Related Topologies
2009In 1852, W. Weber invoked Faraday’s law to suggest that natural diamagnetism could be produced by currents induced in microscopic conducting closed loops, which would be present inside matter. Spirals are well-known designs, widely used in planar microwave circuits as small-size inductors and resonators. However, spirals are low-symmetry structures and,

Light-controllable split-ring resonators
2012 42nd European Microwave Conference, 2012The paper presents a new approach for designing electromagnetic metamaterials which can be controlled by an external light source. The design of light-tunable split-ring resonators loaded by a varactor diode and biased by a photodiode operating in photovoltaic mode is proposed.

Improved shield design for split-ring resonator [PDF]
2015 Third International Conference on Technological Advances in Electrical, Electronics and Computer Engineering (TAEECE), 2015 Shield 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.

Analysis of hexagonal Split Ring Resonator
2016 Progress in Electromagnetic Research Symposium (PIERS), 2016Split Ring Resonator (SRR) is found to be an effective filter at microwave frequencies. Different geometries of SRR can be designed to provide filter characteristics in frequency spectrum. In this paper a novel hexagonal SRR which provides band pass characteristics is presented.

The polarizability matrix of split-ring resonators
Moscow University Physics Bulletin, 2011The resonance behavior of electric and magnetic dipole moment amplitudes that are induced in metallic nanoparticles by the scattering of incident light was obtained by numerical simulation. For a split-ring resonator a full set of polarizability matrix components, including magnetoelectric coupling parameters (bianisotropy), were calculated.

An interdigitated split‐ring resonator for metamaterials
Microwave and Optical Technology Letters, 2010AbstractAn interdigitated split‐ring resonator is proposed and obtains negative permittivity (εr), magnetic permeability (μr), and negative refractive index (n) over a narrow frequency band. This article demonstrates that the proposed structure has a linear frequency response the geometry of the structure and small planar resonators for low frequency ...

Controlling the Bandwidth of Split Ring Resonators
IEEE Microwave and Wireless Components Letters, 2008A method to control the half-power relative band- widths of split ring resonators (SRRs) coupled to a transmission-line system is presented. An equivalent circuit model is proposed to analyze the main factors that effect the relative band- widths of SRRs. Based on the analysis, we propose an efficient way to control the relative bandwidth of SRR, which

A Diplexer with a split-ring resonator junction
2016 Progress in Electromagnetic Research Symposium (PIERS), 2016Diplexers are three-port filtering devices with a junction connecting two channel filters; the common port connects to an antenna which serves the two channel filters bearing the second and the third port. Conventionally, diplexers are designed using transmission line based junctions or circulators, but recently a new approach of designing diplexers ...

Split-ring resonators and localized modes
Physical Review B, 2004The paper presents asymptotic analysis of an eigenvalue problem for the Helmholtz operator in a periodic structure involving split-ring resonators [originally proposed in J. B. Pendry et al., IEEE Trans. Microwave Theory Tech. 47, 2075 (1999)]. The eigensolutions are sought in the form of Bloch waves.

Coupling Between Split-Ring Resonators
AIP Conference Proceedings, 2009Numerical methods have become invaluable tools for research in the field of photonics and plasmonics. The Discontinuous Galerkin Time‐Domain (DGTD) method, complemented by numerous extensions, allows us to solve Maxwell’s equations on unstructured grids while maintaining an efficient, explicit time‐stepping scheme.
