`A newly observed – heliconical (twist–bend) nematic phase (NTB) of nanoscale pitch [1] has recently caught much of attention. Initially, the theoretical concept of this phase has been presented by R. B. Meyer [2] in 1973, where he assumed that the director of the molecules precesses on a cone forming an oblique helicoidal structure. Subsequently in 2001 Dozov [3], in 2002 Memmer [4] and in...

`When encountering a mismatch of characteristic impedance a bulk acoustic wave transforms into up to three reflected and refracted waves of different polarizations. The effect is known as mode conversion. The lack of the specularly reflected wave is called total mode conversion because then all the outgoing waves propagate at speeds different than that of the incident one, what it’s know at...
