How does split ring resonator work?

How does split ring resonator work?

A split-ring resonator (SRR) is an artificially produced structure common to metamaterials. A magnetic flux penetrating the metal rings will induce rotating currents in the rings, which produce their own flux to enhance or oppose the incident field (depending on the SRRs resonant properties).

What is complementary split ring resonator?

Split Ring Resonators (SRR) and Complementary Split Ring Resonators (CSRR) are widely used to simulate metamaterial elements. Such elements are arranged uniformly in a periodic configuration and behave as artificial materials with unusual properties.

What is meant by ring resonator?

An optical ring resonator is a set of waveguides in which at least one is a closed loop coupled to some sort of light input and output. Because only a select few wavelengths will be at resonance within the loop, the optical ring resonator functions as a filter.

What is a split ring commutator?

Split ring commutator: It is the rotating interface of the armature coil with a stationary circuit where the split ring reverses the current at a given point to maintain the shaft torque in a magnetic field. This causes the loop to continuously rotate. Above was the principle of working of an electric motor.

How does a metamaterial antenna work?

Metamaterials used as the antenna environment. Metamaterials are applied as the antennas environment, to improve their radiation properties by using the artificial magnetic conductor (AMC). It is a type of implemented metamaterial in several antennas and microwave design applications.

What is the difference between a split ring and a slip ring commutator?

A split-ring commutator makes the current change direction every half-rotation, whereas a slip-ring commutator merely maintains a connection between the moving rotor and the stationary stator.

What was the purpose of the split ring resonator?

The split ring resonator was a microstructure design featured in the paper by Pendry et al in 1999 called, “Magnetism from Conductors and Enhanced Nonlinear Phenomena”. It proposed that the split ring resonator design, built out of nonmagnetic material, could enhance the magnetic activity unseen in natural materials.

What’s the difference between a split ring and slip ring?

Split-ring resonator consisting of an inner square with a split on one side embedded in an outer square with a split on the other side. Split-ring resonators are on the front and right surfaces of the square grid, and single vertical wires are on the back and left surfaces.

How are SRRs coupled to planar transmission lines?

SRRs have also been coupled to planar transmission lines, for the synthesis of transmission line metamaterials. The split ring resonator was a microstructure design featured in the paper by Pendry et al in 1999 called, “Magnetism from Conductors and Enhanced Nonlinear Phenomena”.

How is the dielectric constant of a ring resonator calculated?

The resonant frequencies obtained were combined with the geometric parameters of the ring resonator and that of the MUT in equations written into MATLAB scripts;this equations were used to extract the dielectric constant of the MUT.
