Controlling the hybridization in stacked split-ring resonators

The influence of dielectric layers on the hybridization of stacked split-ring resonators (SRRs), or SRR dimers, is investigated in this article. It is found that when the permittivity of the layer between the two SRRs is higher than that of free space, the electric dipole-dipole interaction plays a dominant role in determining the modes of resonance. On the other hand, for the case of a free-sp...

Numerical Investigation of Light Scattering off Split-Ring Resonators

It seems to be feasible in the near future to exploit the properties of left-handed metamaterials in the telecom or even in the optical regime. Recently, split ring-resonators (SRR’s) have been realized experimentally in the near infrared (NIR) and optical regime. 2 In this contribution we numerically investigate light propagation through an array of metallic SRR’s in the NIR and optical regime...

Reconfigurable Delay Lines with Split-Ring Resonators

In this paper we proposed anovel multiband delay line which consists of two types of split-ring resonators: the broadiside coupled and the single split-ring resonator. Proposeddelay line exhibits two left-handed bands that can be shifted by twisting the split rings for certain angle or by changing their lengths. This delay line is suitable for design of multiband frequency scanning antennas sin...
