Secluded supersonic elastic surface waves
TL;DR: In this article, it was shown that supersonic surface waves propagating along an axial plane in general directions also exist, and conditions for existence and a few examples are presented.

Two-dimensional ternary locally resonant phononic crystals with a comblike coating
TL;DR: In this paper, an alternative coating profile with a comblike profile is proposed and investigated and the band structures are calculated using the finite element method, and it is shown that a complete bandgap can be induced at a significantly low frequency, the wavelength of which is more than 20 times the lattice constant.

Simple reflection in anisotropic elastic media and its relation to exceptional waves and supersonic surface waves (I): general theoretical considerations
Litian Wang,Jens Lothe +1 more
TL;DR: In this article, a general approach to finding supersonic surface waves in anisotropic materials, some principles concerning the behavior of the eigenvalues of a crucial Br matrix are presented.

Self-orthogonal sextic formalism for anisotropic elastic media: spaces of simple reflection and two component surface waves
Jens Lothe,Litian Wang +1 more
TL;DR: In this article, a self-orthogonal sextic formalism was proposed for the subsonic surface wave theory, and the existence of two component surface waves and supersonic surface waves was shown.

Determination of the ray surface and recovery of elastic constants of anisotropic elastic media: a direct and inverse approach
TL;DR: In this article, the degeneracy analysis approach is used for the construction of the ray surface and the recovery of elastic constants for anisotropic media, and a special emphasis is put on the group velocities along symmetry directions with respect to symmetry planes, for which an explicit expression for the group velocity is given in terms of the elastic constants.
