Аннотация:The effect of dipole-dipole interactions between s urface asperities
on the shift of the local field resonant frequency
has been studied. Expressions have been derived for the acting
field factor as a function of the geometry and surface
density of asperities and the incident radiation polarization.
It has been shown that the collective effects alone may shift
the resonant frequency from the ultraviolet to the optical
and infrared regions
