Design of matching networks transducers
Underwater acoustic transducers convert electrical signals into the longitudinal pressure waves constituting acoustic propagation in water. The mechanical construction of most acoustic transducers (excluding those broad-band receiver transducers known as hydrophones) usually results in narrow-band devices. For example, many projector transducers employed in power drive applications are a develo...
متن کاملMulti-horn matching plate for ultrasonic transducers
The problem of matching a thick piezoelectric transducer to an air medium is considered and it is concluded that a suitable matching device can be designed and built in the form of a rigid plate, a few millimetres thick and pierced by a closely packed array of horn-shaped channels, the wide mouths of the horns facing the external world and the narrow throats facing the transducer. Design parame...
متن کاملLow Cost Matching Network for Ultrasonic Transducers
This paper investigates low cost matching network for high impedance ultrasonic transducers. Matching the output transmitter impedance to high impedance transducer is important to maximize the transfer of power and improve the transmitting efficiency of the transducer, and so achieve better signal-to-noise ratio. In NDT ultrasonic applications based on piezoelectric transducers it is usual to i...
متن کاملBroadband gradient impedance matching using an acoustic metamaterial for ultrasonic transducers
High-quality broadband ultrasound transducers yield superior imaging performance in biomedical ultrasonography. However, proper design to perfectly bridge the energy between the active piezoelectric material and the target medium over the operating spectrum is still lacking. Here, we demonstrate a new anisotropic cone-structured acoustic metamaterial matching layer that acts as an inhomogeneous...
متن کاملMathematical modeling of the radiated acoustic field of ultrasonic transducers
Ultrasonic inspection techniques are widely used for nondestructive evaluation of materials. Mathematical modeling provides an efficient and reliable method to assist the design of the inspection application and the analysis of its results. In this work we use a method based on the Rayleigh-Sommerfeld integral to express the pressure in a fluid generated by different ultrasonic devices like mon...
