hi every one
can any one give me a course or a paper talking about the four waves formalism introduced by Landau and Lifshitz
thanks for advance :)

Do you mean the use of four-vectors in classical field theory in general, or is there something more specific you are thinking of? Is there a particular place in the Landau/Lifshitz series (most likely volume 2) that is giving a problem?

yes i mean the use of four-vectors in classical field theory in general , this formalism is used in the calculation of reflectance and transmission of monolayer multilayered structures

There is a nice little book, "Four-Tensors, the Mother Tongue of Classical Physics", by Reinhart Frosch, that introduces four-tensors and how they are used in classical field theory. It doesn't address how four-vectors are used in reflectance and transmission calculations, but it will help you get the hang of four-tensors if you are not used to them.
