An original formulation for the elastic analysis of multilayered shells is presented in this work. The key features are: representation shell mean surface via a generic system curvilinear coordinates; unified treatment general theories an Equivalent-Single-Layer approach based on through-the-thickness expansion covariant components displacement field; and Interior Penalty discontinuous Galerkin...

By analogy with the electromagnetic wave, the acoustic transparency phenomenon is analyzed for a multilayered sphere with acoustic metamaterials. The neutral-inclusion concept is used to predict the transparency conditions in the quasistatic case, which are further confirmed by a full-wave analysis. The mechanism of the transparency is based on lowering the total-scattering cross section of the...

This paper describes a model for the analysis of multilayered chiral structures containing planar electric and magnetic scattering elements of arbitrary shape, illuminated by an elliptically polarized plane wave. The particular case of a single chiral layer is analyzed and the scattering matrices for single and dual electric and/or magnetic dipole distributions are derived in an original way. A...
