Abstract

In this contribution the use of defect modes in phononic crystals for sensing applications will be discussed on the basis of different practical realizations. As a specific example,
experimental results of wave transmission through tubular phononic crystals will be compared for different materials and in the presence of different geometric defects to the ideal crystal, as well as to reference measurements through a corresponding hollow tube and solid cylinder. Numerical results from finite element models validate the experimental data and are used to illustrate band gap suppression and defect modes.
