Abstract EN
An enhanced plane wave expansion (PWE) method is proposed to solve piezoelectric phononic crystal (PPC) connected with resonant shunting circuits (PPC-C), which is named as PWE-PPC-C.
The resonant shunting circuits can not only bring about the locally resonant (LR) band gap for the PPC-C but also conveniently tune frequency and bandwidth of band gaps through adjusting circuit parameters.
However, thus far, more than one-dimensional PPC-C has been studied just by Finite Element method.
Compared with other methods, the PWE has great advantages in solving more than one-dimensional PC as well as various lattice types.
Nevertheless, the conventional PWE cannot accurately solve coupling between the structure and resonant shunting circuits of the PPC-C since only taking one-way coupling from displacements to electrical parameters into consideration.
A two-dimensional PPC-C model of orthorhombic lattice is established to demonstrate the whole solving process of PWE-PPC-C.
The PWE-PPC-C method is validated by Transfer Matrix method as well as Finite Element method.
The dependence of band gaps on circuit parameters has been investigated in detail by PWE-PPC-C.
Its advantage in solving various lattice types is further illustrated by calculating the PPC-C of triangular and hexagonal lattices, respectively.
