Evanescent wave

 

An evanescent wave is a nearfield standing wave exhibiting exponential decay with distance. Evanescent waves are always associated with matter, and are most intense within one-third wavelength from any acoustic, optical, or electromagnetic transducer. Optical evanescent waves are commonly found during total internal reflection.

Monotonically decaying wave formed when an electromagnetic wave is reflected off an interface between two different transparent dielectrics at an angle greater than the critical angle so that total internal reflection occurs; typically coupled to an electeromagnetic mode (standing wave) inside a waveguide
