The corresponding mathematical model leads to the study of boundary value problems for the Helmholtz and d‘Alembert wave equations in plane domains bounded by periodic curves. In the formal­ ism adopted here these problems are intimately related to the spectral analysis of the L

Introduction,n 1896 [18]., contains an analysis of the scattering of a monochromatic plane wave normally incident on a grating with a sinusoidal profile. In a subsequent paper [19] he extended the analysis to oblique incidence. Rayleigh assumed in his work that in the half-space above the grating the reflected w

Physical Theory,s the principal concepts and results in their simplest forms and without proofs. Moreover, to avoid distracting technicalities the precise conditions for the validity of the results are not always given. Part 1 also contains no references to the literature. All of these ommisions are remedied in Par

Mathematical Theory,hypotheses and full mathematical proofs. The work is based squarely on functional analysis. The reader should have good knowledge of the theory of unbounded selfadjoint operators in Hilbert spaces, as developed in Dunford and Schwartz [9] or any of the many other good texts.
