Coupled wave theory
WebAbstract Rigorous coupled-wave theory of diffraction by dielectric gratings is extended to cover E -mode polarization and losses. Unlike in the H -mode-polarization case, it is shown that, in the E -mode case, direct coupling exists between all diffracted orders rather than just between adjacent orders. © 1983 Optical Society of America Webparameter. The relevant quantity that appears in perturbation theory, coupled-wave theory, and Green’s functions is a volume integral of the form R F·J where F is an …
