  We have continued to develop the theory of Smith-Purcell free-electron lasers * by including the effects of losses in the grating and reflections of the evanescent wave at the ends of the grating. We estimate the magnitude of the reflection coefficient to be about 15 % based on published simulations**, and compute the effect on the start current and the frequency shift. Experiments to observe these effects are underway.
