SENSITIVE ELEMENT FOR MEASUREMENT OF PHYSICAL QUANTITIES ON MAGNETOSTATIC WAVES Russian patent published in 2013 - IPC G01L9/00 G01B7/16 G01K11/00 

FIELD: measurement equipment.

SUBSTANCE: sensitive element consists of substrate layer 4 made on the basis of gadolinium-gallium garnet, material layer 3 epitaxially grown on it, in which magnetostatic waves are spread, for example yttrium-iron garnet, converter 1 of electric signals to magnetostatic wave, constant magnet 5 located under substrate layer 4. A gap is formed between constant magnet 5 and substrate layer 4. Reflecting structures 2 are formed on both sides of converter 1 so that an envelope of pulse characteristic of converter 1 and reflecting structure 2 has, on one side of converter 1, maxima at the time moments corresponding to minima of the envelope of pulse characteristic of converter 1 and reflecting structures 2 on the other side of the converter of electric signals.

EFFECT: increasing sensitivity; reducing losses and enlarging the range of working frequencies above 3 GHz.
