Grating Order Analyzer

The analysis of the diffraction efficiencies of gratings is the typical modeling task for gratings. The efficiencies follow from the Rayleigh coefficients. Both quantities are given for each of the diffraction orders of a grating. VirtualLab Fusion enables the calculation of efficiencies and Rayleigh coefficients by the fully vectorial Fourier modal method (FMM, also known as RCWA). With the help of the Grating Order Analyzer, one can display the efficiencies and Rayleigh coefficients of the distinct orders in various ways.
