I work with Terahertz Technology referring to light with frequencies of 1012 Hz, which is much lower than for visible light and slightly higher of microwaves. Terahertz light has a number of unique capabilities, for instance that it can propagate through most insulating materials such as paper, plastic, cardboard, clothes etc., while being highly sensitive to the chemical composition of larger molecules in most insulating materials and free carriers in conductive materials. For example, we use it to measure complex conductivity in thin films and nanostructures, and complex refractive index in polymers and biomolecules.
