Structural Control of Metamaterial Oscillator Strength and Electric Field Enhancement at Terahertz Frequencies
George R. Keiser, Huseyin R. Seren, Andrew C. Strikwerda +2
The design of artificial nonlinear materials requires control over the internal resonant charge densities and local electric field distributions. We present a MM design with a stru…
Decoupling Crossover in Asymmetric Broadside Coupled Split Ring Resonators at Terahertz Frequencies
George R. Keiser, Andrew C. Strikwerda, Kebin Fan +3
We investigate the electromagnetic response of asymmetric broadside coupled split ring resonators (ABC-SRRs) as a function of the relative in-plane displacement between the two com…
Three Dimensional Broadband Tunable Terahertz Metamaterials
Kebin Fan, Andrew C. Strikwerda, Xin Zhang +1
We present optically tunable magnetic 3D metamaterials at terahertz (THz) frequencies which exhibit a tuning range of ~30% of the resonance frequency. This is accomplished by fabri…
Nonlinear terahertz metamaterials via field-enhanced carrier dynamics in GaAs
Kebin Fan, Harold Y. Hwang, Mengkun Liu +7
We demonstrate nonlinear metamaterial split ring resonators (SRRs) on GaAs at terahertz frequencies. For SRRs on doped GaAs films, incident terahertz radiation with peak fields of…
Frequency-tunable metamaterials using broadside-coupled split ring resonators
Evren Ekmekci, Andrew C. Strikwerda, Kebin Fan +3
We present frequency tunable metamaterial designs at terahertz (THz) frequencies using broadside-coupled split ring resonator (BC-SRR) arrays. Frequency tuning, arising from change…
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…
