| 1 | ### compute the transmitted diffraction orders of a binary grating using mode decomposition |
| 2 | ### based on two different methods: (1) MPB eigensolver and (2) DiffractedPlanewave object. |
| 3 | ### Also, verify that the total power in all the orders is equivalent to the Poynting flux. |
| 4 | ### for normal incidence, compute only positive diff. orders (total transmittance <= 0.50) |
