Abstract :
In this work we discuss our recent investigations in breaking time-reversal and spatio-temporal symmetries to provide novel functionalities in the field of metamaterials, with special emphasis on the field of acoustics and sound manipulation. In particular, we focus on our recent work on non-reciprocal acoustic components and networks of these elements, as well as on the unusual acoustic properties of parity-time symmetric elements and arrays of them.
