FIELD: physics.
SUBSTANCE: method of measuring a physical quantity involves exciting electromagnetic waves in a waveguide resonator, placing the measured object in the wave field of one of the end sections of the waveguide resonator and determining one standing wave characteristic in the object. An identical object with a reference value of the measured physical quantity is placed in the wave field of another end section. The waveguide resonator used can be a section of a long line and its end sections can be identical measuring cells.
EFFECT: simple measuring process and high measurement accuracy.
