Investigation of magnetic resonances for different split-ring resonator parameters and designs
نویسندگان
چکیده
We investigate the magnetic resonance of split-ring resonators (SRR) experimentally and numerically. The dependence of the geometrical parameters on the magnetic resonance frequency of SRR is studied. We further investigate the effect of lumped capacitors integrated to the SRR on the magnetic resonance frequency for tunable SRR designs. Different resonator structures are shown to exhibit magnetic resonances at various frequencies depending on the number of rings and splits used in the resonators. 5 Author to whom any correspondence should be addressed.

Experimental and numerical analyses of the resonances of split ring resonators
The authors investigate the resonances of split-ring resonator (SRR) structures experimentally and theoretically. The transmission measurements were performed on a single SRR unit cell and periodic arrays of SRRs. The magnetic response of the SRR structure was demonstrated by comparing the SRRs’ transmission spectra of with that of closed ring resonators (CRR). The surface currents along the SR...
متن کاملSecond-harmonic optical spectroscopy on split-ring-resonator arrays.
Previous second-harmonic-generation experiments on metallic split-ring-resonator arrays have been performed at fixed fundamental laser center frequency. Here, we perform nonlinear optical spectroscopy on a first set of samples, revealing pronounced resonances. Furthermore, to clarify the role of higher-order split-ring resonances, we perform additional experiments on a second set of samples in ...
متن کاملCoupling effects in low-symmetry planar split-ring resonator arrays.
We introduce a particular low-symmetry (point group of unit cell C(1)) planar periodic arrangement of magnetic split-ring resonators that acts as an effective optical wave plate. We show that this behavior specifically results from the in-plane interactions among the individual split-ring resonators. Measured normal-incidence transmittance and conversion spectra of gold-based samples fabricated...
متن کاملBroadband compact microstrip patch antenna design loaded by multiple split ring resonator superstrate and substrate
We present microstrip patch antenna loaded with multiple split ring resonator substrate and superstrate. We analyze how the loading of split ring resonator superstrate and substrate can improve the bandwidth compared to the simple microstrip patch antenna and microstrip patch antenna loaded with split ring resonator superstrate. Another important observation is made for multiple split ring reso...
متن کاملComplementary Split Ring Resonator Effects on Radiation Pattern Reconfigurable Circular Microstrip Antennas
In this study, a radiation pattern reconfigurable microstrip antenna is designed and fabricated. The antenna’s radiation pattern is directed in 9 different angles by employing a radiating patch and embedding complementary split ring resonators (CSRR) on the ground plane. The radiating patch is of circular shape, while for CSRR elements both circular and rectangular shapes are investigated. The ...
