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...

Gold Asymmetric-Split Ring Resonators (A-SRRs) for Proteins Sensing

In this paper, gold asymmetric-split ring resonators (A-SRRs) are used for proteins sensing in the mid-infrared (IR) spectral region. Self-assembled monolayers (SAMs) of octadecanethiol (ODT) in ethanolic solution were deposited on the resonator surfaces to immobilise protein molecules for their detection. Different diameters ASRRs were fabricated on zinc selenide (ZnSe) substrates using electr...

Microstrip Patch Antenna Miniaturization by using Split Ring Resonators Which Are in-Plane for WLAN Application

Combining the antenna miniaturization and bandwidth preservation could increase the challenges of integrating the smaller, thinner, low profile, high efficient antennas into equipment for different applications. In this paper, a novel Microstrip Patch Antenna with reduced size for WLAN application is proposed. Introducing in-plane Split Ring Resonators (SRRs) in the vicinity of the patch, and f...
