Tunable directional subwavelength acoustic antenna based on Mie resonance
Modulating the emission pattern of classic sound sources with a sub-wavelength scale dimension is a challenging. In this letter, we demonstrate theoretically and experimentally that a Mie-resonance based antenna can be designed in various modes to effectively enhance the emissivity of the radiated p...
