N2 - Long‐range surface plasmon polariton (LRSPP) gratings are studied theoretically via the Lippmann–Schwinger integral equation method. The gratings are composed of a thin gold film (15 nm), which works as a waveguide for LRSPP waves, and an array of equidistant gold ridges on each side of the film designed for Bragg scattering into LRSPP waves at wavelengths around 1550 nm. Out‐of‐plane scattering (OUPS), transmission and reflection into LRSPP waves, and absorption, are investigated with respect to the wavelength, the height of the ridges, and the length of the grating. In particular we calculate the fraction of the light which is lost due to OUPS, and find an asymmetry in the OUPS with respect to wavelength across the bandgap.
