Spectroscopy Cavity with Digital Activation of Millimeter Wave Molecular Headspace

摘要

Millimeter wave energy is provided to a spectroscopy cavity of a spectroscopy device that contains interrogation molecules. The microwave energy is received after it traverses the spectroscopy cavity. The amount of interrogation molecules in the spectroscopy cavity is adjusted by activating a precursor material in one or more sub-cavities coupled to the spectroscopy cavity by a diffusion path to increase the amount of interrogation molecules or by activating the getter material in one or more sub-cavities coupled to the spectroscopy cavity by a diffusion path to decrease the amount of interrogation molecules.
