Wave mixing in coupled phononic crystals via a variable stiffness mechanism [PDF]
, 2016 We investigate wave mixing effects in a phononic crystal that couples the wave dynamics of two channels – primary and control ones – via a variable stiffness mechanism. We demonstrate analytically and numerically that the wave transmission in the primary
