Laboratory Studies of Water Vapor Absorption in Atmospheric EHF Windows

Abstract

A measuring system, comprising a millimeter wave resonance spectrometer and a humidity simulator (RH = 0-101%), for determining absolute absorption by moist air in the 30 to 300 GHz range is described. Performance data and first results obtained at 138 GHz are discussed.
