Abstract. In this paper we consider an automated complex of several
experimental setups for the measurement of dielectric permittivity and magnetic
permeability of samples of small size in the frequency range 2.6 to 33 GHz. Measurements
are performed at fixed frequencies. The main devices used scalar analyzers of
circuits of the type R-2 modified digital output to a personal computer. The central
measuring unit is a resonator of rectangular cross section associated with the
supply line through the coupling element. The diaphragm connection is a thin
metal plate with a slit or a round hole connection. The walls of the resonator
are small holes through which the resonator introduces samples of the test
material. Hole for measuring the magnetic permeability is located on the narrow
wall of the resonator near the short end of the reflector (the end surface). The
second hole, designed to measure the dielectric constant, is made in the wide
wall of the resonator at a distance of quarter wavelength from the end surface.
The system operates at resonance method of measurement. The installation of the
complex is assembled according to a scheme that operates "on
reflection". The effectiveness is demonstrated by measuring the
characteristics of real materials. A comparison
of the obtained results with the data of independent studies. Conformity
of results obtained by two different methods, using different measuring
instruments is quite satisfactory.
Key words: scalar
network analyzers, transmission coefficients, permittivity, permeability, resonance method.
