Therefore, when an acoustic or mechanical wave contacts the material, it perturbs it, generating the unique properties that block sound waves and mechanical vibrations of certain frequencies from passing through.
A small resonator placed in a window pane creates acoustical or mechanical vibrations at just the right frequency to make the glass shatter.
Yan Weili and colleagues at the A * STAR Data Storage Institute have developed a powerful mathematical model that identifies mechanical resonance modes above the Nyquist frequency that lead to vibration, so they can potentially be eliminated, leading to better performing mechatronic systems.
This particular kind of PCN has been shown, by another EPFL scientist, Tobias Kippenberg, to produce mechanical vibrations of different frequencies when it interacts with light.
The magnetic field compresses the metamaterial, but does not constrain it, enabling an acoustic or mechanical wave to perturb the material and generate unique properties, including negative modulus and negative density that blocks sound waves and mechanical vibrations of certain frequencies from passing through.
«Optomechanics is an area of research in which extremely minute forces exerted by light (for example: radiation pressure, gradient force, electrostriction) are used to generate and control high - frequency mechanical vibrations of microscale and nanoscale devices,» explained Gaurav Bahl, an assistant professor of mechanical science and engineering at Illinois.
In particular, the high frequency, high quality - factor mechanical vibrations demonstrated in this work may enable strongly localized, high - sensitivity, optomechanical interaction with chemical and biological samples.»
