Abstract :
The measurement of the dielectric permittivity (????) and loss (????) of liquids at microwave frequencies (4-36 GHz) by the waveguide plunger technique is automated with the help of a single-board microcomputer, based on the Intel 8085 microprocessor. Both the data acquisition and analysis using curve-fitting technique are implemented in this stand-alone dedicated system. Measurements were made with some pure standard liquids, dilute solutions, and compared with literature values.
