Abstract:
The authors have developed a gradient method for the computation of binary dielectric gratings. The method consists in iterative correction of the coordinates of the grating profile and uses an exact differential method to calculate the diffracted field. Analytical matrix representations are obtained for the gradient of the residual functional, which represents the error in the formation of the target intensities of the orders that have passed through the grating. The paper provides the examples of computation of gratings for the formation of 5-11 equal orders.
