Multi-gap individual and coupled split-ring resonator structures.
We present a systematic numerical study, validated by accompanied experimental data, of individual and coupled split ring resonators (SRRs) of a single rectangular ring with one, two and four gaps. We discuss the behavior of the magnetic resonance frequency, the magnetic field and the currents in the SRRs, as one goes from a single SRR to strongly interacting SRR pairs in the SRR plane. We show...
متن کاملDeep subwavelength fourfold rotationally symmetric split-ring-resonator metamaterials for highly sensitive and robust biosensing platform
Metamaterials provide a good platform for biochemical sensing due to its strong field localization at nanoscale. In this work, we show that electric and magnetic resonant modes in split-ring-resonator (SRR) can be efficiently excited under unpolarized light illumination when the SRRs are arranged in fourfold rotationally symmetric lattice configuration. The fabrication and characterization of d...
متن کاملImproved Split - Ring Resonator for Microfluidic Sensing
We present a method of making low loss split-ring resonators for microfluidic sensing at microwave frequencies using silver coated copper wire. We show that a simple geometric modification and the use of square cross-section wire give greater electric field confinement in the capacitive region of the resonant sensor. We use a combination of theoretical analysis, finite element simulations and e...
متن کاملDesign of Wide-Band Metamaterials Based on the Split Ring Resonator Model
It is shown that the highly resonant characteristic of split ring resonator (SRR) can be significantly improved by introducing new pole pairs to Lorentz atomic model, and by adjusting their resonant frequencies and damping terms. A new SRR cell of metamaterials containing all these required poles is then designed for the desired bandwidth.
