Paper Abstract
The scatterometric and electromagnetic signatures of a pattern are computing with the perturbation method combined with the Fourier Modal Method (FMM) in order to reduce computational time. In electromagnetic point of view, the grating is characterized by its scattering matrix which allows the computation of the reflection and transmission coefficient. A slight variation of profile parameters or electrical ones provides a small fluctuation of the scattering matrix, consequently, an analytical expression of the local behavior of its eigenvectors and eigenvalues can be obtained by using a perturbation method.
