Matching region for damped piezoelectric ultrasonic apparatus |
摘要 |
An acoustic impedance match between an ultrasonic transducer and an adjacent transmission medium is obtained, with performance over a relatively wide bandwidth, by providing a special matching region between the transducer and the transmission medium. The matching region includes a layer having a multiplicity of tapered elements. Each of the elements tapers down in size in the direction away from the transducer.
