Abstract
We consider rigorous theories of diffraction gratings in which the electromagnetic field can be considered as infinite series. Numerical implementation of these theories needs truncation of the series. We show that in many circumstances, some properties of the exact solution (conservation of energy, reciprocity relations) are also verified by the truncated solution. Consequently these properties can not be systematically used as a check of validity of the truncated solution.
