日本是较早地开展声表面波技术研究的国家之一,早在1965年大约与美国Voltman等研究叉指换能器同时,日本东北大学柴山乾夫等就开始研究用棱镜等耦合声表面波,多年来日本在声表面波技术的各个方面做了大量的工作,取得了很大进展,尤其在民品开发和生产技术研究方面居领先地位,现在日本的声表面波研究工作仍很活跃,研制生产声表面波器件的厂家也很多,本文只介绍这次访问过的一些 Japan was one of the earliest countries to carry out SAW technology research. As early as 1965, about the same time with the United States Voltman and other research on the interdigital transducer at the same time, Japan’s Tohoku University, such as Chai Shan Fu husband began to study such as the use of prism coupling surface acoustic wave For many years, Japan has done a great deal of work in various aspects of SAW technology and has made great strides. In particular, it has taken the lead in civilian product development and production technology research. Now Japan’s SAW research work is still very active. The development of There are many manufacturers of SAW devices, this article only describes some of the visits this time
