Paper Abstract

The relatively simple measuring methods for determining the complex permittivity and the complex permeability of magnetodielectric materials are presented. Measurement must be done with each sample of any magnetodielectric by two methods: the short circuit method and the idling method. For measurements by the short circuit method, a magnetodielectric sample is placed in the measuring waveguide near the short circuit end. For measurements by the idling method, a magnetodielectric sample is placed in the measuring waveguide at a quarter of the wavelength distance from the short circuit end. The measurements are taken equally for both methods. The measuring waveguide (with a sample) is connected to the standard measuring line. The other end of the measuring line is connected to a transmitter. A transmitter radiates waves of a given frequency, they are reflected by the short circuit end of a measuring waveguide containing a magnetodielectric sample and standing waves are set up. Standing wave parameters can be measured by the standard measuring line and the indicator.
