Phononic canonical quasicrystalline waveguides

I am glad to present a recent set of papers highlighting the noteworthy properties of 1D periodic waveguides generated by a quasicrystalline sequence. The concept of canonical configuration explains how to obtain a periodic frequency spectrum and why this outcome is connected to trace mapping:

In the companion paper, it is shown that quasicrystalline-generated laminates may widen the possibilities to achieve negative refraction, with respect to the typical two-component unit cell, for antiplane shear waves:
