Acoustic emission from a surface-wave-irradiated liquid crystal

Research output: Contribution to journalArticle

Abstract

Evidence of acoustic emission occurring from a homeotropically aligned liquid crystal irradiated by surface acoustic waves has been established. The acoustic emission counts were measured as a function of input signal voltage and cell thickness. It has been observed that the surface acoustic wave intensity required to produce maximum acoustic emission count decreases with increasing cell thickness. The changes occurring in the liquid crystal when subjected to surface acoustic waves were studied using a polarising microscope and the results are explained on the basis of this visual observation.
