Surface plasmons polaritons (SPP) ensure extreme
concentrations of electromagnetic near fields at interfaces
between materials with negative and positive dielectric
permittivity (i.e. between metals and dielectrics), usually several
orders of magnitude compared to fields in free space. This is
useful for a number of practical applications, including chemical
and biological sensing, enhancement of photodetectors and
improvement of photocatalytical reactions. One of the problems
to be solved with plasmonic field localization is that wavevectors
of SPPs may vastly exceed those of propagating waves, so that a
coupling device is mandatory between them. In photocatalytic
microreactors one often uses nanoparticles with localized SPP as
both couplers and field enhancers. In this contribution we
consider the possibility to utilize surface corrugation of thin gold
films to simultaneously ensure coupling between propagating
and plasmon modes and enlarge effective cat...alytic surface. To
this purpose we utilize wet chemical etching (chemical
micromachining). Different surface corrugations are obtained by
varying etching conditions. A combination of gold thin film over
corrugated surface and titanium dioxide nanoparticles is used.
The setup can be used for different photocatalytic processes.
