Abstract

In this talk, we will discuss our recent advances on controlling sound wave via spinning media. First, we study the torque and force a spinning cylindrical column of fluid experiences in evanescent acoustic fields, and show that the resulting discontinuity can scatter sound in unusual ways, e.g., a negative radiation force. In another example, we develop a generalized scattering cancellation theory (SCT) to cloak spinning objects from static observers. Our work extends the applicable realms of SCT to moving objects.
