Abstract: A shock wave barrier comprises a periodic structure having the proper symmetry and local contrast modulation of the acoustic index to divert an incident shock wave by using constructive/destructive interference phenomena that produce a “band gap” in the transmission spectrum of the periodic structure. In general, shock wave energy within the band gap is reflected from the structure. Defect cavities may be formed in the periodic structure to create transmission resonances or “windows” in the band gap. A portion of the incident energy passes through the window and is concentrated in the defect cavities where it is dissipated by other means. The band gap can be quite wide, at least 50% of the center wavelength, and thus can provide an effective barrier from a wide variety of threats with varying blast pressure and range. The structure may be periodic in two or three dimensions providing a band gap barrier in two or three dimensions, respectively.
