Uniqueness in determining rectangular grating profiles with a single incoming wave (Part II): TM polarization case
Jianli Xiang, Guanghui Hu
This paper is concerned with an inverse transmission problem for recovering the shape of a penetrable rectangular grating sitting on a perfectly conducting plate. We consider a gen…

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…
