The theory underlying the measurement of dielectric constants and power Iactors, by means of resonant lengths of coaxial transmission line, is developed, apparatus used for such measurements is illustrated and the measurement routine described. A table of typical results is appended together withan “X tan X” table for aid in the calculations.read more

Microwave Dielectric Measurements
T. W. Dakin,C. N. Works +1 more
TL;DR: In this paper, the dielectric properties of some common plastic and ceramic materials at 10 cm and 3 cm wave lengths were measured using a short circuited end of the transmission line, and the properties of the sample, calculated from the position of a minimum of the standing wave and the ratio of the minimum field strength to the maximum field strength, were given.
