Scattering of P-polarized evanescent waves by a spherical dielectric particle

Optical Holography Reconstruction of Nano-objects

“…The present results were obtained in the range of visible optics and agree well with the experimental results found by Mugnai et al (Mugnai et al, 2001(Mugnai et al, & 2004 in the microwave range; both phenomena are described very well by the three-coronae theoretical model. Experimental data are consistent also with the results of a theoretical study recently carried out by Ayyagari and Nair (Ayyagari and Nair, 2009) on the scattering of p-polarized evanescent waves by a dielectric spherical particle.

Holography at the Nano Level With Visible Light Wavelengths

“…The obtained results have been confirmed by a formal solution of the problem of a sphere illuminated by evanescent illumination utilizing Debaye's potentials [18]. There are two important aspects of the analysis of the formation of the sphere's diffraction pattern to be highlighted.…”

“…λ=0.6328 μm). The indices of refraction n pp and n ps of the ordinary and extraordinary beams travelling in the optical system were determined by combining equations (18)(19)(20) The obtained results support the assumptions concerning the presence of systems of lines in the captured images and their source in the residual stresses present on the glass of the prism.…”

“…The second terms of the equations (18,19) are the Maxwell-Neumann equations that relate the absolute retardations to the principal stresses σ 1 and σ 2 . In the current case, since residual stresses are both compressive, it holds σ 1 < σ 2 .…”
