We design actively-controlled metastructures to realize autonomous and reprogrammable guiding of acoustic/mechanical waves. This includes: (i) waveguding inspired by quantum mechanics, (ii) waveguding by feedback-based generation of user-defined parameters for unconventional wave transmission, reflection and bending, (iii) real-time creation of wave absorbers and artificial acoustic fields, and more. Our research is multi-disciplinary, combining Control Theory, Acoustics, Vibrations, Physics and Electronics. Our work is of a theoretical/computational character, targeting realistic physical systems.
