Abstract
As a kind of new intelligent materials, liquid crystal elastomer (LCE) has attracted widespread interest. In this paper, we introduce LCE into chiral phononic crystal (CPC), and investigate the properties of band structures based on the iterative calculation method. The effects of dextral bending angle, chiral geometric parameters [Formula: see text] and [Formula: see text], and the director rotation angle on bandgaps are mainly discussed. This work is a meaningful try for application of LCE in acoustic field and propose a new strategy in designing of PC with tunable bandgaps.
