Circular Sound Wave Scattering Derivation for Acoustic Cloak Detection
Circular Sound Wave Scattering Derivation Acoustic Cloak Detection Classical Physics
2012/5/29
In this Letter we develop analytical formulations to describe sound scattering in lossless medium due to 2D circular wave incident on an acoustic cloak. A perfect acoustic cloak is reflectionless and ...
Effective speed of sound in phononic crystals.
Renormalized waves and thermalization of the Klein-Gordon equation: What sound does a nonlinear string make?
Renormalized waves thermalization Klein-Gordon equation
2010/11/10
We study the thermalization of the classical Klein-Gordon equation under a u^4 interaction. We numerically show that even in the presence of strong nonlinearities, the local thermodynamic equilibrium ...
