Abstract The diffraction of a slowly varying input beam incident upon a nonuniform grating is studied. Expressions for the diffracted field at the output of the grating are first derived relying on well known kinematic and coupled wave theories. A third approach based on Fourier expansions of both the input beam and the quasi-periodic grating is then introduced and shown to provide the same expression under certain simplifying assumptions. The advantages of the approach for the solution of more general problems are discussed.
