Subwavelength imaging refers to the ability to visualize and resolve features that are smaller than the wavelength of the light used in imaging systems. This technique is particularly important in applications where conventional optical systems struggle, allowing for enhanced resolution and detail in imaging at nanoscale levels. Its implementation is significantly advanced through the use of metamaterials and metasurfaces, which manipulate electromagnetic waves in unique ways, enabling the capture of intricate details that are otherwise hidden from standard imaging methods.
