Abstract
In a new type of terahertz (THz)-to-infrared converter for the visualization of THz radiation sources, nanoparticles are embedded in a THz-transparent matrix material. The nanoparticles are made of a metal or an alloy having a partially filled peak of the electron density of states at the Fermi energy. The converter is designed to operate with the THz objective forming a source's image on the matrix, wherein the irradiated nanoparticles convert THz energy to thermal energy, whose spatial distribution is captured by an infrared camera. Nickel nanoparticles are very appropriate for high-frequency THz radiation and can find application in real-time passive imaging of biomedical objects at room temperature. Nanoparticles of compounds with heavy fermions are suitable for low-frequency THz radiation, which could be used to image concealed objects carried by a human being.
