Abstract :
The nature of the bulk near-surface light radiation arising in the conditions of surface electromagnetic wave excitation by finite-size input grating has been theoretically studied. The electromagnetic fields associated with SEW were taken from the known expressions for infinite grating solved problem. The results shown that in addition to SEW there exists another surface-bulk wave propagating on smooth part of the surface
