Abstract

We study the problem of reaching maximal sensitivity of microwave spectrometers. The comparative analysis of the spectroscopy methods is carried out. Novel method based on the phase switching of radiation is presented. The calculation carried out show that spectrometer realizing this method provides the best approach to the theoretical limit of sensitivity. Description of the phase switched and some experimental results have been given.
