This reflection forms the evanescent wave which extends into the sample.

The angle provided for total internal reflection and setting up an evanescent wave.

Furthermore, as the evanescent waves are now amplified, the phase is reversed.

Superlensing results from the enhancement of evanescent waves by surface plasmons.

The evanescent waves quickly dissipate as they travel, and thus are usually not seen.

The light again illuminates the glass block, and an evanescent wave penetrates through the metal film.

More generally, practical applications of evanescent waves can be classified in the following way:

In this case, an evanescent wave is produced, which rapidly decays from the surface into the second medium.

This can easily cause images based on evanescent waves or surface plasmon interference to disappear.

The wave is reflected at the plasma surface due to the skin effect and becomes an evanescent wave.
