Inertial amplification of continuous structures: Large band gaps from small masses
TL;DR: In this article, the authors investigate wave motion in a continuous elastic rod with a periodically attached inertial-amplification mechanism, which has properties similar to an "inerter" typically used in vehicle suspensions, but here it is constructed and utilized in a manner that alters the intrinsic properties of a continuous structure.
