Superlinsen
Superlinsen, also known as "super lenses," are a type of optical device that can overcome the diffraction limit, a fundamental constraint in conventional optics that limits the resolution of imaging systems. This limit, often referred to as the Abbe diffraction limit, dictates that the smallest feature that can be resolved is approximately half the wavelength of the light used. Superlinsen achieve sub-diffraction imaging by exploiting phenomena such as surface plasmon polaritons or near-field interactions.
One common approach involves using a thin layer of a specific material, often a metal like silver
Another type of superlens utilizes the principle of near-field optics. In this scenario, the imaging device
