Far-field acoustic subwavelength imaging and edge detection based on spatial filtering and wave vector conversion
The resolution of acoustic imaging suffers from diffraction limit due to the loss of evanescent field that carries subwavelength information. Most of the current methods for overcoming the diffraction limit in acoustics still operate in the near-field of the object. Here we demonstrate the design an...
