A system of computer controlled transmission lines based on the method of traveling waves is presented, permitting the precise detn. of complex permittivities of medium to high loss liqs. at 8.5 to 90 GHz. It consists of a newly developed app. for the E-band region (60 ≤ v/GHz ≤ 90), which is described in detail, together with existing X- (8.5 ≤ v/GHz ≤ 12.4), Ku- (12.4 ≤ v/GHz ≤ 18), and A-band (26.4 ≤ v/GHz ≤ 40) set-ups now appropriately adapted for computer control. Consistency and accuracy of the equipment are evidenced with the help of permittivity data for water, methanol, N-methylformamide, DMF.
