Claim 0:
1. A method for determining electromagnetic fields associated with a mask model of a patterning process, the method comprising:
obtaining, with a hardware computer system, a mask stack region of interest, the mask stack region of interest being divided into sub regions, the mask stack region of interest having one or more characteristics associated with propagation of electromagnetic waves through the mask stack region of interest;
generating, with the hardware computer system, one or more electromagnetic field determination expressions based on the Maxwell Equations and the Quantum Schrodinger Equation; and
determining, by the hardware computer system, an electromagnetic field associated with the mask stack region of interest based on the sub regions of the mask stack region of interest and the one or more characteristics associated with the propagation of electromagnetic waves through the mask stack region of interest, using the one or more electromagnetic field determination expressions.
