Radiation field angled horn antenna with a piezoceramic transducer with radial polarization
Hydroacoustic antenna in which reflector is designed as an acoustically soft angled horn and the sound source is cylindrical piezoceramic transducer with radial polarization, is considered. The internal cavity of transducer is filled with an elastic medium, which is typical for transducers both power and compensated designs. Problem of sound radiation of such an antenna in "through" setting solved using methods related fields and partial areas. All physical fields of antenna are presented in the form of expansions in Fourier series whose coefficients are determined by the joint solution of differential equations describing the electro-elastic vibrations of a piezoceramic transducer and wave processes in acoustic mediums, that is in contact with him. The problem is reduced to the solution of an infinite system of linear algebraic equations relative to the coefficients of expansions.
