Abstract
PURPOSE: To convert only the magnetostriction elastic waves from one direction into electric signal, by placing the zigzag type conductive constituent at the both sides of the non-crystal magnetostriction elastic body with a given distance.
CONSTITUTION: The pitch of the folding path of the zigzag type coils 4, 4' is p, and the folding path of the zigzag type coil 4 placed on the surface of the non- crystal magnetostriction thin plate 1 and the coil 4' placed at the rear surface is placed shifted by P/2. By flowing the current from the signal source 5 for the two zigzag type coils 4, 4' to the 90° phase shifter 6, the synthesized magnetic field M caused in the non-crystal magnetostriction thin plate 1 by the coils 4, 4' represents the progressing magnetic field propagating with the speed u toward X direction. The Joule effect due to the progressing magnetic field causes magnetostriction to the non-crystal magnetostriction thin plate 1, exciting elastic waves travelling a direction together with the progressing magnetic field
