2021 46th International Conference on Infrared, Millimeter and Terahertz Waves (IRMMW-THz).
We use optical pump—terahertz (THz) probe spectroscopy to investigate ultrafast sheet conductivity dynamics in various epitaxial graphene layers grown on SiC. Inhomogeneities in graphene layers developed during the growth are at the origin of confi

The dynamics of plasmons in nanoribbons of (hydrogen intercalated) quasi-freestanding single-layer graphene is studied by terahertz spectroscopy both in the steady state and upon photoexcitation by an ultrashort near infrared laser pulse. The use of

Abstract Antiferromagnetic CuMnAs thin films have attracted attention since the discovery of the manipulation of their magnetic structure via electrical, optical, and terahertz pulses, enabling convenient approaches for switching between magnetoresis

Metamaterials XI.
Dielectric spheres with high permittivity represent a Mie resonance-based metamaterial. Owing to its high far-infrared permittivity and low dielectric losses, TiO2 is a suitable material for the realization of magnetic metamaterials based on micro-re

Polarized terahertz transmittance and infrared reflectivity measurements were performed on selected lead zirconate crystals at T = 10 K. The fit of the spectra enabled us to obtain all three principal components of its anisotropic dielectric function

Dielectric terahertz (THz) resonators of sub-wavelength size, as compared to free-space wavelength at resonance, are essential building blocks for the emerging all-dielectric THz technology. We experimentally and numerically study the effects of mate

Using the near-field time-domain terahertz spectroscopy, we detect the splitting of magnetic dipole resonance mode in strongly anisotropic mono-crystalline TiO 2 micro-spheres. By fitting the Fano resonance model to the experimental data, we extract
