Tailoring the slow light behavior in terahertz metasurfaces
Manukumara Manjappa, Sher-Yi Chiam, Longqing Cong +3
We experimentally study the effect of near field coupling on the transmission of light in terahertz metasurfaces, possessing slightly distinctive SRR resonances. Our results show t…
Controlling metamaterial resonances via dielectric and aspect ratio effects
Sher-Yi Chiam, Ranjan Singh, Weili Zhang +1
We study ways to enhance the sensitivity and dynamic tuning range of the fundamental inductor-capacitor (LC) resonance in split ring resonators (SRRs) by controlling the aspect rat…
Analogue of Electromagnetically Induced Transparency in a Terahertz Metamaterial
Sher-Yi Chiam, Andrew A Bettiol, Ranjan Singh +3
We experimentally demonstrate at terahertz frequencies that a planar metamaterial exhibits a spectral response resembling electromagnetically induced transparency. The metamaterial…
Observation of a New Magnetic Response in 3-Dimensional Split Ring Resonators under Normal Incidence
S. Y. Chiam, A. A. Bettiol, M. Bahou +3
So far, research in the field of metamaterials has been carried out largely with arrays of flat, 2-dimensional structures. Here, we report a newly identified magnetic resonance in…
New assembly route for three-dimensional metamaterials through effect medium theory
Jiaguang Han, Sher-Yi Chiam, Ee Jin Teo +2
In this study, we illustrate the effective medium theories in the designs of three-dimensional composite metametails of both negative permittivity and permeability. The proposed me…
