Magnetic and electric excitations in split ring resonators

Optics Express, 2007
We studied the electric and magnetic resonance of U-shaped SRRs. We showed that higher order excitation modes exist in both of the electric and magnetic resonances. The nodes in the current distribution were found for all the resonance modes. It turns out that the magnetic resonances are the modes with odd-number of half-wavelength of the current wave,

Design and Fabrication of Compact, Multiband, High Gain, High Isolation, Metamaterial-Based MIMO Antennas for Wireless Communication Systems

Micromachines, 2023
We proposed a novel approach based on a complementary split-ring resonator metamaterial in a two-port MIMO antenna, giving high gain, multiband results with miniature size. We have also analyzed a circular disk metasurface design.

Controlling split-ring resonators with light [PDF]

Applied Physics Letters, 2011
We propose an original approach for creating tunable electromagnetic metamaterials. We demonstrate experimentally that magnetic resonance of a split-ring resonator (“meta-atom” of a composite material) with a photodiode operated in photovoltaic mode can be tuned by changing the intensity of an external light source. Moreover, for two coupled resonators,

Split-Ring Resonator-Loaded Baffles for Decoupling of Dual-Polarized Base Station Array

IEEE Antennas and Wireless Propagation Letters, 2020
Baffles loaded by split-ring resonator (SRR) are proposed to reduce the mutual coupling for ±45° dual-polarized multiple-input–multiple-output (MIMO) antenna. Each baffle consists of two rectangular SRR printed on one side of a 1 mm FR4 substrate.

An antenna-coupled split-ring resonator for biosensing

Journal of Applied Physics, 2014
An antenna-coupled split-ring resonator-based microwave sensor is introduced for biosensing applications. The sensor comprises a metallic ring with a slit and integrated monopole antennas on top of a dielectric substrate. The backside of the substrate is attached to a metallic plate.
