ABSTRACT:
A device is provided for estimating the electromagnetic characteristics of a dielectric or magnetic material by means of a hyperfrequency electromagnetic wave which device comprises a coaxial line formed of a tubular body (2,3) and a core (1), which are rigid and coaxial with, at one end, a housing such that the external and internal peripheries of an annular sample piece (17) are respectively in tight friction contact with the inner surface of said tubular body and with the external surface of said core, said tubular body being formed of two parts which can be assembled together.
