  The dielectric properties of complex plasma containing either metal or
dielectric spherical inclusions (macroparticles, dust) are investigated. We
focus on surface plasmon resonances on the macroparticle surfaces and their
effect on electromagnetic wave propagation. It is demonstrated that the
presence of surface plasmon oscillations significantly modifies plasma
electromagnetic properties by resonances and cutoffs in the effective
permittivity. This leads to related branches of electromagnetic waves and to
the wave band gaps. The results are discussed in the context of dusty plasma
experiments.
