Nanoscale double asymmetric split ring resonators

SPIE Proceedings, 2011
Double asymmetric split ring resonators (DA-SRRs) are composed of four separate asymmetric metallic arcs that share the same centre-of-curvature. These four arcs interact to produce very steep slopes in the reflection spectrum and also increase the number of trapped modes.

Controlling the Bandwidth of Split Ring Resonators

IEEE Microwave and Wireless Components Letters, 2008
A 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

An interdigitated split‐ring resonator for metamaterials

Microwave and Optical Technology Letters, 2010
AbstractAn 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 ...

Light-controllable split-ring resonators

2012 42nd European Microwave Conference, 2012
The 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.

Spectroscopy of Individual Split-Ring Resonators

Frontiers in Optics 2008/Laser Science XXIV/Plasmonics and Metamaterials/Optical Fabrication and Testing, 2008
We measure the absolute extinction cross-section spectrum of the magnetic resonance of individual split-ring resonators by a modulation technique. The experimental data are in excellent agreement with numerical calculations.

Analysis of hexagonal Split Ring Resonator

2016 Progress in Electromagnetic Research Symposium (PIERS), 2016
Split 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.

Split-ring resonators and localized modes

Physical Review B, 2004
The 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.

The polarizability matrix of split-ring resonators

Moscow University Physics Bulletin, 2011
The 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.

Supershaped complementary split-ring resonators

2017 USNC-URSI Radio Science Meeting (Joint with AP-S Symposium), 2017
This paper investigates the possibility of using complementary split ring resonators based on Gielis transformation as basic elements for the design of microwave filters implemented in planar technology. From the electromagnetic simulation of these structures, suitable equivalent circuit models are extracted and analyzed.

Coupling Between Split-Ring Resonators

AIP Conference Proceedings, 2009
Numerical 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.
