Refraction close refractionProcess by which a wave changes speed and sometimes direction upon entering a denser or less dense medium, eg a light ray changes direction when refracted by a lens. from a ...
Bound states in the continuum (BICs) are a special class of resonant states. Although they have the same momentum and energy as the propagating modes in free space, yet they are not coupled to the ...

Evanescent waves

Exploring the physics phenomenon where light waves penetrate a boundary even when total internal reflection occurs. Demonstrating how these non-propagating waves exist and their crucial role in ...
