The book reviews the properties of surface plasmons that depict
electromagnetic surface waves or surface plasma polaritons. Their
propagation on smooth and corrugated surfaces (with rough or grating
profiles) is considered. In the latter case, the corrugations can cause
strong coupling of the surface plasmons with photons leading to
resonances with a strong enhancement of the electromagnetic field in the
surface. Coupling and field enhancement are the most prominent phenomena
on corrugated surfaces and lead to numerous important applications.
Attention has been focused on the explanation of the physics. To keep
the text readable, sophisticated calculations have been avoided, and
instead various applications dealing with enhanced light emission,
nonlinear optics, SERS, and other cases of interest are discussed.
