The Design of a Linear, Passive, Nonreciprocal, Electroacoustic Transducer,

Abstract

The design of an electroacoustic transducer which in linear and passive, and yet nonreciprocal is described. Emphasis is placed on the design of a particular type of such a transducer because of its possible use in wake homing torpedoes. This transducer has a transmitting-directivity pattern of the single-main-lobe, or searchlight type, and a receiving-directivity pattern of the split-lobe type. This type of nonreciprocity is achieved by combining two different kinds of electroacoustic transducer elements into one instrument. One element must be a condenser or piezoelectric crystal assembly, and the other an electromagnetic or electrodynamic transducer. (Author)
