Creeping waves, also known as "creeping line waves" or "surface waves," refer to a type of electromagnetic wave propagation that occurs along the surface of a dielectric material, such as the surface of a conductor or the interface between two media with different electromagnetic properties. These waves "creep" along the surface rather than propagating freely through the bulk of the material or space.
