The factorization method for the Drude-Born-Fedorov model for periodic chiral structures
We consider the electromagnetic inverse scattering problem for theDrude-Born-Fedorov model for periodic chiral structures known as chiral gratingsboth in $\mathbb{R}^2$ and $\mathbb{R}^3$. The Factorization methodis studied as an analytical as well as a numerical tool for solving this inverse problem.The method constructs a simple criterion for characterizing shape of the …
