摘要: Abstract This work describes a new technique for constructing both linear and matrix array transducers. It used completely separated piezoelectric elements whose vibration modes have been studied experimentally. Each element has λ 4 matching plate backing, so it forms separate transducer. The is formed by an assembly of these shows some interesting features such as the possibility reducing dispersion electroacoustic characteristics single to required value, mechanical strength, periodical maintenance.
