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.

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 ...

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

Plasmon resonance in split-ring resonator based heterostructures
Materials Express, 2023We herein propose a plasmonic nanostructure that is composed of heterogeneous metallic split-ring resonator (SRR) trimers with built-in crosses. We studied its optical transmission properties by using finite difference time domain (FDTD) method. Results showed that, the resonant modes can be changed when the nanostructures are composed of different ...

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.
