Reflection of Plane-Polarized, Electromagnetic Radiation from an Echelette Diffraction Grating

Abstract
A variational method is used to calculate the distribution of energy reflected from an echelette diffraction grating. Experiments performed using a klystron generating 3.2‐cm electromagnetic waves which impinge upon a large scale grating agree with the calculations to within a few percent, the error being that expected from the variational formulation.
