FIELD: measurement engineering.
SUBSTANCE: the method consists in the fact that in a rectangular waveguide that is short-circuited at the end, with a longitudinal slot on its side wall, which in the process of measurement is closed by a short-circuiting switch or by the specimen under measurement, before the process of measurement the air gap between the waveguide and the specimen under measurement or standard is filled in with solder.
EFFECT: enhanced accuracy of measuring information on the value of complex dielectric permittivity of low-impedance composite materials.
