Abstract:
The experimental techniques of attenuated total reflection and grating-coupling were originally employed separately
as probes for surface polaritons. However, as far back as the mid-1970s, some value was found in actually combining
them into a single tool for probing elementary surface excitations. In this article, the theory of the two methods
combined into one probe for surface polaritons is presented. The main results of the calculations, here, are the firstorder
diffuse reflectivities, which arise due to the presence of a classical grating. For the ease of presentation, only a
semi-infinite specimen is considered and the grating is thought to be deposited only on one interface. The discussion
highlights the advantages the combined technique has over either of the two methods when each is employed on its own.
