Effect Of The Support

I. Theoretical and experimental studies of supported spherical metal particles show that the existence of the support introduce some new surface plasmon modes. As a continuation of our previous work, hydrodynamics theory is used to calculate the plasmon frequencies of the half-embedded spherical particles as a function of the particle sizes. In this study, the spatial dispersion effects of the particle sizes are illustrated. The predicted surface plasmons ⍵h and ⍵LO, as in Fig. 1(A), and ⍵1 to ⍵4 as in Fig. 1(B) are for the cases of a metal A1 particle covered with thin Al2O3 layer sitting on (A) a dielectric insulator AlF3 and (B) a metallic AI plate, respectively. The detailed model description is given in, The dotted solid curves in Fig. 1 are plots of the surface plasmon frequencies for an isolated metal particle. It is clearly seen that the appearance of ⍵LO and ⍵1, ⍵2, and ⍵4, for the two different supporting cases, are due to the existence of the support. It shows that the effect of the support on the metal particle properties must be considered in the practical experiments.

Surface Plasmon Polariton Mode

Abstract Total internal reflection ellipsometry was employed for the excitation and study of hybrid Tamm plasmon-surface plasmon polaritons mode. Simple optical methodology using optical filters to cut the part of incident light spectra was proposed. Using optical filters measured energy spectra was divided into two parts where in each range only one branch of the hybrid TPP-SPP plasmonic mode was excited directly by the incident light. Present experimental studies have shown, that if the investigated system is in strong coupling, this is always enough to excite only one component of the hybrid excitation. Thus, its dispersion relation will be the same as when the excitation is done with a whole spectrum. In the case of the TPP-SPP hybrid mode where strong coupling is realized only in p-polarized light, the fitting results have shown that the strongest coupling was at the point where the noninteracting TPP and SPP curves should be crossing. The obtained Rabi splitting for the hybrid TPP and SPP modes in BK7 prism/1D PC TiO2/SiO2 (60 nm/110 nm)/TiO2 (30 nm)/Au (40 nm) multilayered structure was about 105 meV.

Tissue Culture Line

Mammalian spindles are generally large and may contain over a thousand microtubules (MTs). For this reason they are difficult to reconstruct in three dimensions and many researchers have chosen to study the smaller and simpler spindles of lower eukaryotes. Nevertheless, the mammalian spindle is used for many experimental studies and it would be useful to know its detailed structure.We have been using serial cross sections and computer reconstruction methods to analyze MT distributions in mitotic spindles of PtK cells, a mammalian tissue culture line. Images from EM negatives are digtized on a light box by a Dage MTI video camera containing a black and white Saticon tube. The signal is digitized by a Parallax 1280 graphics device in a MicroVax III computer. Microtubules are digitized at a magnification such that each is 10-12 pixels in diameter.
