Abstract: When a charged particle crosses an interface between two different materials, electromagnetic radiation called Transition Radiation is emitted. The spectrum of this radiation extends up to x-ray domain. The Resonant Transition Radiation (R.T.R.) can be observed with a periodic arrangement of interfaces. The R.T.R. in the soft x-ray range has been recently measured by K. Yamada and coll. with a Nickel-Carbon multilayer structure [1]. In this paper, a rigorous electromagnetic theory of the R.T.R in finite and infinite multilayer structures is developed using the matricial formalism and compared with the experimental quoted data [1].
