Mode spectrum of noncollinear electroacoustic boundary-guided waves in a ferroelectric with a moving strip domain

Electroacoustic Waves in a Ferroelectric Crystal with of a Moving System of Domain Walls

“…Below, on the basis of our works [Vilkov, 2008;Vilkov, 2009;Vilkov et al, 2009] the propagation of guided EIWs and bulk electrosound waves in a dynamic superlattice of equidistant uniformly moving 180-degree DW is considered. Let's notice, that until now the research of acoustic effects in crystals of ferroelectrics with moving DW was limited to cases of noncollective acousto-domain interactions:a single DW [Shevyakhov, 1990;Gulyaev et al, 2000], a strip domain (i.e., a pair of DWs) [El'meshkin & Shevyakhov, 2006] and a structure of a two adjacent strip domains [Bugaev et al, 2005].…”
