Description

technical field [0001] The invention relates to a planar nanometer electromagnetic radiator structure based on negative differential mobility. Background technique [0002] Terahertz (THz) waves occupy a very special position in the electromagnetic spectrum, and their frequency range is roughly 0.1-10THz (THz=1012Hz). In the long-wave direction, it overlaps with millimeter waves; in the short-wave direction, it overlaps with infrared rays. Due to its special position, THz waves have a series of special properties: in the frequency domain, terahertz is in the transition zone from macroscopic classical theory to microscopic quantum theory, and in the transition from electronics to photonics; The rotation and oscillation frequency of various macromolecules; its quantum energy is very low, and it will not cause damage to matter; so compared with X-rays, it has great advantages, and it will definitely become a research tool for various substances—— Especially living matter - a ...
