title = "Investigation of Ultrasonic Opacity Based on Quarter-Wave Mode Resonance Using a Two-Dimensional Silicon Phononic Crystal",
abstract = "We present a class of phononic crystals for ultrasonic opacity. This composite membrane composed of a host plate made of silicon in which the unit cell describes a sub-wavelength quarter-wave resonator embedded in water. The finite element simulations have shown that such acoustic metamaterial constitutes an ambitious category of ultrasonic insulator providing a deep and wide attenuation in the transmission spectrum. This attenuation reaches −30 dB in a 66% relative bandwidth.",
