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

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.

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.

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 ...

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,

Nanoscale double asymmetric split ring resonators
SPIE Proceedings, 2011Double 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.
