A comprehensive classified list of annotated references on surfaces which combine high solar absorptance with low thermal emittance is presented, covering the period 1955–1981. The list embraces papers printed in scientific journals and in published conference proceedings. An index of authors and on surface coatings studied is appended.

Surfaces for selective absorption of solar energy: an annotated bibliography 1955–1981

Homogenization theory deals with asymptotic methods in periodic structures. In this paper we apply these methods to the study of a dielectric or conducting grating when the spacing of the grating, supposed to be periodic with respect to x, tends to zero. We prove, from a mathematical point of view, that it is in effect possible to replace the groove region by a stratified layer whose optical index is x-independant. Our results, obtained in a rigorous way, confirm and strengthen those foreseen by colleagues of the University of Sydney.

Homogenization Techniques as Applied in the Electromagnetic Theory of Gratings

In this chapter we will consider the theoretical analysis and the properties of doubly periodic diffraction gratings (“bigratings”). Our interest in these structures has been stimulated by two factors. Firstly, their theoretical study represents a natural extension of previous work on mono-periodic structures. Secondly, HORWITZ [7.1] suggested the use of metallic grids as selective filters (heat mirrors) in solar energy absorption. Of course such devices have application in far infrared spectroscopy as beam splitters [7.2], filters [7.3–5] and the reflecting elements in Fabry-Perot interferometers [7.5–10]. Similar applications exist in the field of microwave engineering [7.11.13].

Theory of Crossed Gratings

Some difficulties frequently encountered when dealing with the theory of electromagnetic waves are illustrated with the help of examples taken from the work of our laboratory. We also lay stress on some recent results and the appendix contains two propositions concerning the completeness of some sequences of functions often used to expand the electromagnetic fields.

On the roles of physical intuition, computation, and mathematical analysis in electromagnetic diffraction theory

Les reseaux ou les reseaux croises traces sur un materiau de conductivite finie constituent un modele simple de surface rugueuse. Nous avons donc essaye de predire, a partir des equations de Maxwell, l'absorption de la lumiere visible par ces surfaces particulieres. Nous rendons compte ici de nos premieres conclusions en insistant sur les difficultes rencontrees.
