Size and Periodicity Effects on Terahertz Properties of Gammadion Metamaterials
Daniel M. Heligman, A. M. Potts, N. Crescimanno +4
We studied the effects on the terahertz transmission of gammadion metamatials by adjusting the size and periodicity of the metamaterial, while keeping the periodicity and size fixe…
Corrective Re-gridding Techniques for Non-Uniform Sampling in Time Domain Terahertz Spectroscopy
A. M. Potts, T. T. Mai, M. T. Warren +1
Time domain terahertz spectroscopy typically uses mechanical delay stages that inherently suffer from non-uniform sampling positions. We review, simulate, and experimentally test t…
Terahertz Dielectric Analysis and Spin-Phonon Coupling in Multiferroic GeVS
Matthew T. Warren, G. Pokharel, A. D. Christianson +2
We present an investigation of the multiferroic lacunar spinel compound GeVS using time-domain terahertz spectroscopy. We find three absorptions which either appear or shif…
Terahertz Spin-Orbital Excitations in the paramagnetic state of multiferroic SrFeSiO
Thuc T. Mai, C. Svoboda, M. T. Warren +5
We studied the novel multiferroic material SrFeSiO, and found 3 absorption modes above the magnetic ordering transition temperature using time-domain terahertz spectros…
