Abstract

To study the origin of the SNOM image contrast patterns observed for samples of transparent materials only, we have investigated the transmission SNOM images of an ordered polystyrene particles layer for various wavelengths of incident light. We have found a drastic change in the SNOM image patterns as the incident wavelength is scanned across the resonant wavelength of the photonic bands of the layer. Observed wavelength dependence of the near-field intensity of the layer was found to be in a good qualitative agreement with the theoretical calculation in terms of the photonic band effect.
