Abstract :
The Lorentz reciprocity theorem is used to derive an identity which is helpful in examining the accuracy of solutions to periodic metal-surface scattering problems. The identity checks the amplitude and phase of individual propagating space harmonics while the more familiar criterion of energy conservation checks the total accumulated power.
