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…

Uniqueness in determining binary grating profiles and refractive indices with a single incoming wave
Jianli Xiang, Guanghui Hu
We investigate inverse diffraction problems for penetrable gratings in a piecewise constant medium. In the TE polarization case, it is proved that a binary grating profile together…
