摘要

声表面波（SAW）在自旋电子学、量子声学和电子量子光学等多个领域具有巨大潜力，但声表面波生成电路产生的电磁波往往是一大障碍。在此，我们研究了一种数字间换能器的差分激励方法，以在产生声表面波的同时减少电磁波。结果表明，电磁波在所有方向上都被抑制了 90% 以上。这种抑制克服了声表面波系统的操作限制，提高了其可扩展性。我们的研究成果有望促进基于声表面波的应用在广泛研究领域的发展。

Suppression of electromagnetic crosstalk by differential excitation for SAW generation

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. Here, we investigate a differential excitation method of interdigital transducers to generate SAWs while reducing the electromagnetic wave. The results show that electromagnetic waves are suppressed by more than 90 % in all directions. This suppression overcomes the operating limits and improves the scalability of SAW systems. Our results promise to facilitate the development of SAW-based applications in a wide range of research fields.
