The laws and effects of terahertz wave interactions with neurons
Frontiers in Bioengineering and Biotechnology, 2023 Introduction: Terahertz waves lie within the energy range of hydrogen bonding and van der Waals forces. They can couple directly with proteins to excite non-linear resonance effects in proteins, and thus affect the structure of neurons.

Graphene hyperlens for terahertz radiation [PDF]
Physical Review B, 2012 We propose a graphene hyperlens for the terahertz (THz) range. We employ and numerically examine a structured graphene-dielectric multilayered stack that is an analogue of a metallic wire medium. As an example of the graphene hyperlens in action we demonstrate an imaging of two point sources separated with distance $ _{0}/5$.

Non-destructive testing of fiber-reinforced composites by terahertz method
Research and Review Journal of Nondestructive Testing, 2023 Fiber-reinforced composites are materials that are increasingly replacing metals in many construction solutions. Damage to the composite structure may occur both as a result of technological errors in the production phase and during operation as ...

Bow-Tie Cavity for Terahertz Radiation [PDF]
Photonics, 2018 We report on the development, testing, and performance analysis of a bow-tie resonant cavity for terahertz (THz) radiation, injected with a continuous-wave 2.55 THz quantum cascade laser. The bow-tie cavity employs a wire-grid polarizer as input/output coupler and a pair of copper spherical mirrors coated with an unprotected 500 nm thick gold layer ...
