A New Method for Measuring Dielectric Constant and Loss in the Range of Centimeter Waves

摘要

In 1940, dielectric measurements in the centimeter range were considered as difficult and not very accurate. The authors, therefore, developed a ``hollow‐pipe'' method which overcame these objections and required only a weak oscillator and small amounts of the dielectric material. The theory and its practical applications, as perfected by March 1941, are presented in this paper.
