Analysis and design of focused interdigital transducers

IEEE Transactions on Ultrasonics, Ferroelectrics and Frequency Control, 2005
Focused interdigital transducers (FIDTs) can generate surface acoustic wave (SAW) with high intensity and high beamwidth compression ratio. Owing to these features, they are very suitable to be used as the sources of microacoustic channels or waveguides in the near future. The focusing properties of FIDTs are dominated solely by their geometric shapes.

Acoustic Focusing Device With an Interdigital Transducer

Journal of the Acoustical Society of America, 1977
We have devised a new type of simple acoustic focusing device with an interdigital transducer in which all radiation from each section of the transducer constructively interferes at a focal point in water. The position of the focal point of the device is variable by changing the carrier frequency of an electrical signal applied to the transducer.

Electromagnetic Leakage Suppression by Interdigital Transducers

Proceedings of the IEEE, 1975
A simple interdigital transducer layout is used in conjunction with a differential amplifier to obtain a high degree of suppression of direct electromagnetic leakages in surface acoustic wave devices. The degree of suppression can be adjusted independently of the device design.

Subwavelength Focusing of Surface Acoustic Waves Generated by an Annular Interdigital Transducer

Applied Physics Letters, 2008
International audienceWe propose and demonstrate experimentally the concept of the annular interdigital transducer that focuses acoustic waves on the surface of a piezoelectric material to a single, diffraction-limited, spot. The shape of the transducing

SAW Filters Employing Interdigitated Interdigital Transducers, IIDT

1982 Ultrasonics Symposium, 1982
Over the p ast decade a vast effort by numerous groups has produced a wide range of SA\! filters with impressive performance characteristics. Unfortunately most such filters have losses of 20 to 30 dB, which makes them unsuitable for frontend applications.
