Broadband Characterization of Near-Field Focusing With Groove-Structured Lens

Subdiffraction focusing of acoustic waves in the near-field can remarkably improve the signal-to-noise ratio in super-resolution acoustic imaging. Recently, we have successfully demonstrated the feasibility of near-field focusing with groove-structured lens. However, as a very critical step toward p...
