      In this example, the mode losses due to radiation into a high index substrate for the fundamental mode of an SOI waveguide will be calculated with the FEEM solver. This requires the use of PML boundary conditions, which were added to the FEEM solver in release 2021 R1.4. The results with different mesh settings will be compared to simulation results from the literature through convergence testing.
