Non-sequential Field Tracing

Non-sequential field tracing of two coupled gratings. Following the non-sequential interconnection of two grating regions leads to a rigorous iterative solution of the coupled system. In comparison to the reference result from global S matrix calculation, it is shown that non-sequential field tracing results converges to the true values.

As one of the fundamental strategies in field tracing, an optical system is divided into regions which can be modeled with a specialized regional solver, and then the interconnection of all regions delivers the solution to the complete system. Following Neumann's series, it can be shown that a non-sequential interconnection of all regions leads to a rigorous iterative solution of the system, given that numerical convergence is reached.
