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…
Wireless transfer of power by a 35-GHz metamaterial split-ring resonator rectenna
Carsten Maedler, George Keiser, Adrian Yi +9
Wireless transfer of power via high frequency microwave radiation using a miniature split ring resonator rectenna is reported. RF power is converted into DC power by integrating a…
Terahertz Saturable Absorption in Superconducting Metamaterials
George R. Keiser, Jingdi Zhang, Xiaoguang Zhao +2
We present a superconducting metamaterial saturable absorber at terahertz frequencies. The absorber consists of an array of split ring resonators (SRRs) etched from a 100nm YBaCu3O…
Nonlinear terahertz devices utilizing semiconducting plasmonic metamaterials
Huseyin R. Seren, Jingdi Zhang, George R. Keiser +6
The development of responsive metamaterials has enabled the realization of compact tunable photonic devices capable of manipulating the amplitude, polarization, wave vector, and fr…
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…
