Abstract : The resonance condition of a leakymode propagating in a dielectric multilayer, which is supported by a mirror and excited by a free space wave from the cover medium, is simply derived from the phase of the reflection at the mirror and cover interfaces. The leaky mode resonance is used to obtain 100% -1st order diffraction efficiency in a reflection resonant grating by destructive interference in the direction of Fresnel reflection. A number of examples support the validity of this condition for high efficiency and illustrate the usefulness of this intelligible representation of the diffraction phenomena for the synthesis of novel diffractive elements.
Keywords : waveguide Gratings leaky waves nonhomogeneous media resonance waveguide.
