Abstract :
THE best ways to measure the dielectric properties of materials with high dielectric constant are described throughout the frequency range from 100 to 1,000 mc. The principles of measurement of dielectric properties at ultrahigh frequencies are well established. They are based on measurement of voltage standing wave ratio and location of standing wave pattern, which results from reflection of electromagnetic energy from the dielectric sample.
