作为第一个可实现电整流的器件,电子二极管的发明标志着现代电子学的诞生,并在全球范围内引发了各个领域内的革命,最终深刻地改变了我们的整个生活.声波作为一种重要的经典波,具有比电磁波更为悠久的研究历史及更为普遍的存在形式.因此,若能设计并实现一种可像电子二极管控制电流那样对声能量进行整流的声学器件,这将对声学的器件制造、实际应用乃至整个声学研究领域都产生重大影响,其学术意义及应用价值的重要性不言而喻.文章详细介绍了利用超晶格与非线性声学材料构成的声二极管的理论与实验方面的最新研究进展.
As the first device to implement electrical rectification, the invention of electronic diodes marks the birth of modern electronics and has sparked revolutions in all fields around the world, ultimately profoundly changing our entire life. An important classical wave has a longer history and a more general form of existence than electromagnetic waves, so if one can design and implement an acoustic device that can rectify acoustic energy like an electronic diode control current, Acoustic device manufacturing, practical application and even the entire field of acoustic research have a significant impact, its academic significance and the importance of the value of the application is self-evident.This article describes in detail the theory of using superlattice and nonlinear acoustic materials composed of acoustic diodes With the latest experimental research progress.
