The evanescent waves in geometrical optics and the mixed hyperbolic-elliptic type systems
Enrico De Micheli, Giovanni Alberto Viano
In this article we describe the generation of the evanescent waves which are present in the rarer medium at total reflection by using a mixed-type system, the Ludwig system, which…
