Comprehensive modeling of interferometric hydrophone with self-supported mandrel transducer

A novel design of an interferometric hydrophone transducer is presented. It consists of a coil of fiber embedded in a layer of epoxy. Finite Element modeling of such transducer is difficult due to anisotropic mechanical properties of its structure. An approach based on laminate modeling techniques was adopted. Static and modal Finite Element analysis was conducted, as was a coupled-field acousto-mechanical analysis.
