ИСТИНА

In my lecture, I will talk about the basic principles of building terahertz sensor devices that can be used to study small impurities in the atmospheric air, including human waste products and pathogens. Increased sensitivity of sensors is achieved by using dielectric metamaterials, which contribute to the concentration of the electric field near the characteristic anomalies in the absorption and refraction spectra of complex organic molecules. I will talk about methods to achieve extreme concentration detection of impurity substances in the atmospheric air. Important for practical application is not only the sensor itself, but also the corresponding source of terahertz radiation, which is tuned to the optimal resonance of the molecule-sensor system.
