Fiber-drawn double split ring resonators in the terahertz range

Terahertz metamaterials with semiconductor split-ring resonators for magnetostatic tunability.

We studied a metasurface constituted as a periodic array of semiconductor split-ring resonators. The resonance frequencies of the metasurface excited by normally incident light were found to be continuously tunable in the terahertz regime through an external magnetostatic field of suitable orientation. As such metasurfaces can be assembled into 3D metamaterials, the foregoing conclusion also ap...

Transmission properties of terahertz pulses through subwavelength double split-ring resonators.

We present a terahertz time-domain spectroscopy study of the transmission properties of planar composite media made from subwavelength double split-ring resonators (SRRs). The measured amplitude transmission spectra reveal a resonance near 0.5 THz, the central frequency of most ultrafast terahertz systems, for one SRR orientation in normal-incidence geometry. This resonance is attributed to the...

Equivalent Circuit Model for Double Split Ring Resonators

This article focuses on the electric modeling of split ring resonators with a new approach based on an equivalent circuit. The elements of circuit are determined from geometric parameters forming the three dimensional model of this type of resonators. In the first part, an analytic study is proposed about the determination of the components of the circuit according to a function of physical par...
