The waves always 'spread' to some extent into the area beyond the gap. This is diffraction - the spreading out of waves when they go through a gap, or past the edge of a barrier. The extent of the ...

Several approaches are capable of beating the classical 'diffraction limit ... where evanescent waves have faded, cannot be far from that given by the well-known Abbe–Rayleigh rule, according ...

The film explains the concept of electromagnetic waves, particularly focusing on their applications in radar, radio, and television. It describes how a crystal set functions as a simple radio receiver ...

Captured here is a laser diffraction pattern, visible as a series of concentric circles with a bright central area. This pattern is a result of light waves spreading out and overlapping after passing ...

Surface lattice resonance, where the dipoles (represented as arrows) in nanodisks are coupled via in-plane diffraction (waves between the disks oscillating perpendicular to the arrows) Bound ...

A new design architecture, called diffraction casting ... Essentially, optical computing leverages the speed of light waves ...
