We have measured the terahertz spectrum of pure l-tyrosine at nineteen temperatures in the range 6K to 300K using a synchrotron as the source of radiation. By fitting the temperature dependence of the observed modes with a Bose-Einstein model, we determine unequivocal low-frequency modes of l-tyrosine at absolute zero temperature occur at 1.02 ± 0.01 ...

Modern Terahertz-subTerahertz (THz-subTHz) spectrometers, based on continuously frequency-tunable coherent sources of radiation, the backward-wave oscillators (BWOs), are described which cover the frequencies v = 1 cm−1 − 50 cm−1 (0.03 − 1.5 THz) and allow for measurements at temperatures 2 − 1000 K, also in magnetic fields.

Terahertz interface physics: from terahertz wave propagation to terahertz wave generation
Journal of Physics D: Applied Physics, 2022Abstract Terahertz (THz) interface physics as a new interdiscipline between the THz technique and condensed matter physics has undergone rapid development in recent years. In particular, the development of advanced materials, such as graphene, transitional metal dichalcogenides, topological insulators, ferromagnetic metals, and ...

We present a concept for the design of photoconductive antennas which allows the generation and detection of terahertz radiation pulses of freely selectable modes. We demonstrate the principle by showing electric field distributions for vector beams, namely the lowest order Gaussian-Bessel beams. They have a donut-like intensity distribution and either

Reconfigurable Terahertz Metamaterials
Physical Review Letters, 2009We demonstrate reconfigurable anisotropic metamaterials at terahertz frequencies where artificial "atoms" reorient within unit cells in response to an external stimulus. This is accomplished by fabricating planar arrays of split ring resonators on bimaterial cantilevers designed to bend out of plane in response to a thermal stimulus.

Terahertz plasmonic composites
Physical Review E, 2007The dielectric response of a polymer matrix composite can be substantially modified and tuned within a broad frequency band by integrating within the material an artificial plasmon medium composed of periodically distributed, very thin, electrically conducting wires.

Terahertz semiconductor-heterostructure lasers
Summaries of Papers Presented at the Lasers and Electro-Optics. CLEO '02. Technical Diges, 2002Semiconductor devices have become indispensable for generating electromagnetic radiation in everyday applications. Visible and infrared diode lasers are at the core of information technology, and at the other end of the spectrum, microwave and radio-frequency emitters enable wireless communications. But the terahertz region (1-10 THz; 1 THz = 10(12) Hz)
