Abstract:
We show that narrow optical band pass filters can be created by means of
nanoparticles which consist of a dielectric sphere and a metallic shell.
The components can be adjusted such that
there is a remarkable transparency at the desired
wavelength range, while a strong absorption takes place outside of this region.
