    <description descriptionType="Abstract">&lt;p&gt;A hybrid Finite Element-Plane Wave Expansion method is presented for the&lt;br&gt;
band structure analysis of phononic crystal plates with two dimensional lattice&lt;br&gt;
that are in contact with acoustic half-spaces. The method enables the computation&lt;br&gt;
of both real (propagative) and imaginary (attenuation) components of&lt;br&gt;
the Bloch wavenumber at any given frequency.&lt;br&gt;
Three numerical applications are presented: a benchmark dispersion analysis&lt;br&gt;
for an oil-loaded Titanium isotropic plate, the band structure analysis of a waterloaded&lt;br&gt;
Tungsten slab with square cylindrical cavities and a phononic crystal&lt;br&gt;
plate composed of Aurum cylinders embedded in an epoxy matrix.&lt;/p&gt;</description>
