Abstract:
Much of the recent interest in terahertz radiation stems from its ability to penetrate deep into many organic materials, without the damage associated with ionizing radiation such as X-rays and its applications in modern medical therapy and imaging. In this work we report the results of studies related to radiative properties of moving and standing water in the terahertz spectral range. The transmission of such radiation through holes of various sizes (0.2-4mm) was analyzed by detecting it on the photographic film. Emission of millimeter-wave radiation can be explained by the transition of water molecule from the higher rotational states to the lower one. Terahertz emission from different liquids which have strong rotational transitions have been registered.
