Finite element and integral equation methods to conical diffraction by imperfectly conducting gratings
Guanghui Hu, Jiayi Zhang, Linlin Zhu
In this paper we study the variational method and integral equation methods for a conical diffraction problem for imperfectly conducting gratings modeled by the impedance boundary…

Well-posedness of grating diffraction problems for plane wave incidence: explicit dependence on wavenumbers and incident angles
Linlin Zhu, Guanghui Hu
Suppose that a plane wave is incident onto an impenetrable grating profile of Dirichlet or Impedance type or a penetrable grating. The grating interface is assumed to be given by a…
