Temporal negative refraction
Or Lasri, Lea Sirota
Negative refraction is a peculiar wave propagation phenomenon that occurs when a wave crosses a boundary between a regular medium and a medium with both constitutive parameters neg…

Real-Time Steering of Curved Sound Beams in a Feedback-based Topological Acoustic Metamaterial
Lea Sirota, Daniel Sabsovich, Yoav Lahini +2
We present the concept of a feedback-based topological acoustic metamaterial as a tool for realizing autonomous and active guiding of sound beams along arbitrary curved paths in fr…

Non-Newtonian Topological Mechanical Metamaterials Using Feedback Control
Lea Sirota, Roni Ilan, Yair Shokef +1
We introduce a method to design topological mechanical metamaterials that are not constrained by Newtonian dynamics. The unit cells in a mechanical lattice are subjected to active…
