The vector theory is developed and employed to calculate 1-D aerial images by numerically solving Maxwell's equations to account for the scattering effect from realistic mask structures. Comparisons of results from the scalar and vector theories are made for conventional chrome mask and various phase shifting masks to show the differences of these two theories
