Characteristics and Applications of Electromagnetic Surface Wave Transducers [PDF]

, 1977
Tom Szabo mentioned during his presentation that there is a great deal of similiarity between the response of a meander line surface wave EMT and that of an interdigital transducer. We have been investigating their common properties to see if they can be

Suppression of electromagnetic crosstalk by differential excitation for SAW generation

Applied Physics Express
Surface acoustic waves (SAWs) hold a vast potential in various fields such as spintronics, quantum acoustics, and electron-quantum optics, but an electromagnetic wave emanating from SAW generation circuits has often been a major hurdle.

On-chip stimulated Brillouin scattering via surface acoustic waves

APL Photonics
Surface acoustic wave devices are ubiquitously used for signal processing and filtering, as well as mechanical, chemical, and biological sensing and show promise as quantum transducers. While surface acoustic waves (SAWs) are primarily excited and driven

Analysis of acoustics surface wave reflection on the interdigital transducer

Archives of Acoustics, 2014
By applying the equivalent scheme, the analysis of the acoustics surface wave reflection from the interdigital transducer has been carried out. The explicit form of the coefficient of reflection was found, from which the following terms have been ...
