Studies on Phononic Band Gaps of Periodic Hollow Cylinders in the Air

Gang Wan

Abstract

Band gaps of 2D phononic crystal, composed of square arrays of periodic hollow stainless steel cylinders in the air, are analyzed both theoretically and experimentally. The effects of lattice constant on band gaps are also discussed. It is concluded that while the lattice constant is decreased, the width and the limit frequency of the band gap of ΓX-direction increased.
