DEVICE TO MEASURE INTENSITY OF ELECTRIC FIELD OF MAGNETIC TYPE WAVE IN WAVE GUIDE Russian patent published in 2015 - IPC G01R29/08 

FIELD: measurement equipment.

SUBSTANCE: invention relates to measurement devices for determination of intensity of electric field of a magnetic type wave in a wave guide. The device represents a combination of miniature β-spectrometer and an electron gun, which are mounted on a tubular vacuumized wave guide. Measurements with the help of the proposed device are carried out in the following manner. The flux of electrons injected by the electron gun passes via the wave guide, through which waves of magnetic type spread, and the intensity of electric field of which changes according to the law: $$\overrightarrow{E}={\overrightarrow{E}}_o\sin (\omega t+{\phi }_o).$$ At the same time a part of the flux of electrons gets into a phase of maximum value of electric field intensity. Then electrons get into a β-spectrometer, with the help of which using the available method they fix the maximum value of electric field intensity in the surveyed wave guide.

EFFECT: technical result of this invention is development of an instrument for direct and accurate measurement of electric field intensity in waves of medium and high capacity and magnetic type in a tubular wave guide.
