Study on Filling Fraction of Bandgap Lowest Starting Frequency of one Dimension Phononic Crystals

Abstract:

A calculation method of lowest band gap starting frequency corresponding to filling fraction of fixed periodic size one dimension phononic crystals are given, found the filling fraction only correlation with the density of two materials, but no correlation with elastic modulus, furthermore found no correlation with periodic size.
