Structurally Tunable Nonlinear Terahertz Metamaterials using Broadside Coupled Split Ring Resonators
George R. Keiser, Nicholas Karl, Sheikh Rubaiat Ul Haque +3
We present an experimental and numerical study of a terahertz metamaterial with a nonlinear response that is controllable via the relative structural positioning of two stacked spl…
Comparison of Birefringent Metamaterials and Meanderline Structure as Quarter-Wave Plates at Terahertz Frequencies
Andrew C. Strikwerda, Kebin Fan, Hu Tao +3
We have fabricated a quarter-wave plate from a single layer birefringent metamaterial. For comparison, an appropriately scaled double layer meanderline structure was fabricated. At…
Electronic control of extraordinary terahertz transmission through subwavelength metal hole arrays
Hou-Tong Chen, Hong Lu, Abul K. Azad +5
We describe the electronic control of extraordinary terahertz transmission through subwavelength metal hole arrays fabricated on doped semiconductor substrates. The hybrid metal-se…
