Rigorous analysis of extremely asymmetrical scattering of electromagnetic waves in slanted periodic gratings
T. A. Nieminen, D. K. Gramotnev
Extremely asymmetrical scattering (EAS) is a new type of Bragg scattering in thick, slanted, periodic gratings. It is realised when the scattered wave propagates parallel to the fr…
Extremely asymmetrical scattering in gratings with varying mean structural parameters
D. K. Gramotnev, T. A. Nieminen, T. A. Hopper
Extremely asymmetrical scattering (EAS) is an unusual type of Bragg scattering in slanted periodic gratings with the scattered wave (the +1 diffracted order) propagating parallel t…
Non-steady-state double-resonant extremely asymmetrical scattering of waves in periodic gratings
Dmitri K. Gramotnev, Timo A. Nieminen
Double-resonant extremely asymmetrical scattering (DEAS) is a strongly resonant type of Bragg scattering in two joint or separated uniform gratings with different phases. It is cha…
Grazing-angle scattering of electromagnetic waves in gratings with varying mean parameters: grating eigenmodes
D. K. Gramotnev, S. J. Goodman, T. A. Nieminen
A highly unusual pattern of strong multiple resonances for bulk electromagnetic waves is predicted and analysed numerically in thick periodic holographic gratings in a slab with th…
