Transmission spectra of bilayers of a strongly absorbing dye molecule on thin semitransparent metallic films show a pronounced variation of the shape as a function of the thickness of the metal film. The shape changes with increasing thickness of the metal film from the form of an absorption spectrum as determined by the imaginary part of the dielectric(More)
A triangular nanoaperture in an aluminium film was used previously as a probe in a scanning near-field optical microscope to image single fluorescent molecules with an optical resolution down to 30 nm. The high-resolution capability of the triangular aperture probe is because of a highly confined spot of the electric near field which emerges at an edge of(More)
A description is given of an experimental technique that improves the accuracy of the measurement of light extinctions by polarized light microscopy from deposits of pyrolytic carbon. The measurements were performed using a specially developed digital photometric image-analysis procedure providing high spatial and angular resolution of light extinctions(More)
This article is devoted to an observation artefact arising in near-field optical calculations by methods with the discretization of a scattering object and the substitution of separated dipoles instead of discretizing meshes. It is discussed that such an artificial discretization gives within the object a non-monotonously changing field on the scale of the(More)
