A boundary integral formulation is presented for computing the scattering from infinite periodic gratings. Periodic boundary conditions and expansion of the fields in terms of Floquet harmonics allow the boundary integral formulation to treat just a single period of the infinite grating. Numerical results for a blazed grating designed for use at infrared wavelengths are presented and shown to be in good agreement with a series of measurements. © 1992 John Wiley & Sons, Inc.
