Abstract
In this paper, the plane wave expansion (PWE) method is used to obtain the band structure of 1D phononic crystals (PnCs). Inherent to all real systems, geometry, material property and boundary condition uncertainties can be included in the model to evaluate the system uncertainty. The main goal is to analyse the effect of uncertainties in parameters of the metamaterials-based structures and how it can influence the Bragg-type band gaps of 1D PnC rods. The band structure is obtained and presented by including the effect of the uncertainty in Young's modulus.
