ABSTRACT:
A method for generating a simulated aerial image of a mask projected by an optical system includes determining a coherence characteristic of the optical system. A coherent decomposition of the optical system is computed based on the coherence characteristic. The decomposition includes a series of expansion functions having angular and radial components that are expressed as explicit functions. The expansion functions are convolved with a transmission function of the mask in order to generate the simulated aerial image.
