Elastic wave propagation along a 1D chain of pillars
Résumé
We theoretically investigate with the help of the finite element method the interaction between
aluminum pillars erected on top of a silicon substrate in the low frequency range. We investigated the resonant
modes of a finite linear chain of N pillars and demonstrate the propagation along the chain of pillars deposited
on the half-infinite substrate. Different configurations of the chain will be investigated from periodic, linear and
bent, to random distributions.
