Lossy gratings with a finite number of grooves: A canonical model
We consider here the scattering of a plane wave at a flat boundary characterized by a coordinate-dependent surface impedance that varies periodically only over a finite region. This surface impedance represents a wide class of scattering structures that includes finite-diffraction gratings. Numerica...

| Sumario: | We consider here the scattering of a plane wave at a flat boundary characterized by a coordinate-dependent surface impedance that varies periodically only over a finite region. This surface impedance represents a wide class of scattering structures that includes finite-diffraction gratings. Numerical results are obtained to show the adequacy of this canonical model. © 1992 Optical Society of America. |
