The fundamental optical excitations that are confined to a
metal/dielectric interface are the surface plasmon polaritons
(SPPs), as described by Ritchie. SPPs can be referred to as
electromagnetic excitations existing at an interface between two
media, of which at least one is conducting. Investigating spoof
plasmons in a semiconductor is becoming an increasingly active area
of research. The field of plasmonics deals with the application of
surface and interface plasmons. It is an area in which surface
plasmon-based circuits merge the fields of photonics and
electronics at the nanoscale. Recently, an idea of engineering
surface plasmons at lower frequencies was suggested. It was
concluded in that the existence of holes in the structure can lower
the frequency of existing surface plasmons. Thus, by cutting holes
or grooves in metal surfaces, it is possible to take concepts such
as highly localized waveguiding and superfocusing to lower
frequencies, particularly to the THz regime, where plasmonics could
enable near-field imaging and biosensing with unprecedented
sensitivity. It is the main reason to use the terminology "spoof
surface plasmons" for the bound surface waves propagating along the
perforated structures. The book's title Spoof Plasmons demonstrates
that it is devoted to exhibiting the current state of the art of
the dynamic and vibrant field of photonic metamaterials reaching
across various disciplines, suggesting exciting applications in
chemistry, material science, biology, medicine, and engineering.
