Far-field acoustic subwavelength imaging and edge detection based on spatial filtering and wave vector conversion
Plasmonic effects and subwavelength scattering arrays are used in the optical domain to access subwavelength resolution imaging in the far field. Here, the authors develop an analogous strategy for far-field, subwavelength imaging at acoustic wavelengths and demonstrate edge detection of acoustic sc...
