Abstract

A study is made of the effect the aperture and the number of electrode pairs of an interdigital transducer (IDT) have on the characteristics of acoustic signals A₁ and SH₁ excited in a LiNbO₃YX-plate. The obtained dependences of signal intensity on the experimental parameters demonstrate the possibility of miniaturizing integrated sensors consisting of a array of sensors based on delay lines or single IDT resonators.

叉指换能器的孔径对其在压电板上输出信号特性的影响

摘要

研究了叉指式换能器（IDT）的孔径和电极对数量对在LiNbO ₃ YX板中激发的声信号A ₁和SH ₁的特性的影响。所获得的信号强度对实验参数的依赖性证明了使集成传感器小型化的可能性，该集成传感器由基于延迟线或单个IDT谐振器的传感器阵列组成。
