Analysis of liquid-core cylindrical acoustic waveguides

Transmission properties of guided modes in liquid-core cylindrical acoustic waveguides are investigated. It is observed that for each value of the circumferential order n the first mode becomes of Stoneley-type above a certain frequency. There are two modes without cutoff frequencies, in contrast to...

Description
Summary:	Transmission properties of guided modes in liquid-core cylindrical acoustic waveguides are investigated. It is observed that for each value of the circumferential order n the first mode becomes of Stoneley-type above a certain frequency. There are two modes without cutoff frequencies, in contrast to only one mode in solid-core waveguides. They are the first modes with n=0 and 1. The application of liquid-core waveguides in sensor devices is pointed out and some preliminary experimental results are reported.
