SapienzaTerahertz: THz spectroscopic image system for basic and applied sciences

Lingua Italiano

The laboratory is equipped with

a state of the art Quantum Cascade Laser (QCL) THz sources with emission powers in the mW range and between (1.9-5) THz;

a state of the art 2D sensor composed of microbolometers at room temperature (and other pyroelectric sensors).

a high resolution (down to 10 MHz) coherent spectroscopy system at THz frequencies composed by a combination of photoantennas and IR lasers in optical fiber.

Ultra-focal magnetic stimulation using a µTMS coil: a computational study

A new miniaturized figure-of-eight coil (μCoil) for TMS applications has been developed taking advantage of the Flex circuit technology. First experiments on volunteers demonstrated the ability of the μCoil to elicit sensorial action potentials of the peripheral nervous system. The necessity of reducing the size of standard TMS stimulator arises from the poor spatial resolution of the latter. This study aims to model the μCoil and study the electromagnetic fields induced inside the arm during peripheral nerve stimulation.
