Experimental evidence of bandgap structures in the lower jaw of the bottlenose dolphin (tursiops truncatus)
conference contribution
posted on 2012-03-26, 13:09 authored by S.A. Dible, James A. Flint, Paul LepperPaul LepperPrevious studies using the TLM numerical modelling technique have demonstrated the potential
existence of bandgap structures within the lower jawbone of the Atlantic Bottlenose dolphin
(Tursiops truncatus). The study presented here shows experimental evidence of the existence of
these bandgaps within a 2-D structure that mimics the prinnciple dimensions of the lower teeth and
jawbone of the Bottlenose dolphin. The bandgap present is due to the tooth structure in the lower
jaw forming a periodic array of scattering elements, which results in the formation of an acoustic
stop band that is angular dependent.
