Abstract

PURPOSE:To extend the frequency region of elastic waves, by changing the folding distance in position for the zigzag type conductive constituent. CONSTITUTION:When high frequency current is flown to the input zigzag type coil 4, high frequency magnetic field according to the Ampere's theorem is developed around the folding path of the input zigzag type coil 4. Although distortion is caused with the joule effect for the non-crystal magnetostriction thin plate of the folding coil 4 by this magnetic field, since the distortion depends not on the direction of magnetic field but on the absolute value, the magnetostriction pulse group can be developed corresponding to the location of the folding path of the zigzag type coil 4 and the folding distance to the thin plate 1.
