Gravity-induced dispersion in a chiral waveguide: transient regimes and imperfect temporal interfaces

Abstract

The paper includes analysis of an elastic chiral waveguide, subjected to gravity, where a coupling between different displacement components is assumed owing to gyroscopic action. The importance of gravity and chirality on the dispersion of waves is demonstrated and behaviour in all regimes, including asymptotic ones, is addressed and linked to the value of the chirality parameter. In the transient regimes, we analyse chiral imperfect temporal interfaces in the waveguide subjected to gravity.
