Abstract: A magnetostrictive transducer comprising a plurality of elongated strips of magnetostrictive material, each strip having a proximal end and a distal end and being attached to its adjacent strip at the ends to form an integral substantially rigid column having a central axis with fins extending radially relative to said axis; and an ultrasonic resonant vibrator including such a transducer.
