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.

Interaction of twisted split ring resonators
2011 Conference on Lasers and Electro-Optics Europe and 12th European Quantum Electronics Conference (CLEO EUROPE/EQEC), 2011We study the dynamics of two microwave split ring resonators broadside coupled to each other, varying twist angle θ between them, as shown in Fig. 1(a). A similar system operating at near infra-red frequencies was presented in [1]. We show our experimental and numerical results in Fig. 1(b).

Asymmetric split ring resonators for organic sensing
2009 11th International Conference on Transparent Optical Networks, 2009We have previously reported the use of asymmetric split ring resonators for sensing organic material in the infra red [1]. Arrays of circular split ring resonators can be tuned to particular wavelengths in the mid infra red. By producing asymmetry in the structures, the two sides of the ring produce plasmon resonances that are reflection peaks and a ...

A novel millimeter wave super lens using split-ring resonator and complementary split-ring resonator
2009 34th International Conference on Infrared, Millimeter, and Terahertz Waves, 2009We report a millimeter wave super lens based on the left-handed metamaterial using split-ring resonator (SRR) and complementary SRR (CSRR). The millimeter wave cannot propagate far away due to short wavelength. Therefore, the system for THz or millimeter wave band demands the lens to obtain strong focused signal from weak waves caused by scattering in ...

11th International Symposium on Antenna Technology and Applied Electromagnetics [ANTEM 2005], 2005
The study that is done in this paper compares the physical phenomena observed when placing a 50Ω microstrip line on respectively a periodic lattice of SRRs and a SSRRs defected ground plane. In both cases, a band-stop phenomenon is observed, but the coupling with the microstrip line is completely different.

2010 International Conference on Microwave and Millimeter Wave Technology, 2010
Microstrip line periodically loaded with split-ring resonators (SRRs) and complementary split-ring resonators (CSRRs) is designed. By utilizing the CSRRs/gaps and SRRs/inductances combinations, two passbands are observed. Because of the negative permeability offered by SRRs and series capacitances, the negative permittivity offered by CSRRs and shunt ...
