We investigate experimentally far-field scattering from cylinders with illumination non-uniform along the axis of the cylinder. Scattered intensity as a function of angle in two orthogonal directions is examined. Variation along the scattering angle is found to be little affected by the illumination profile. However, variation in the transverse direction follows closely the Fourier transform of...

The electrostatic interaction between two parallel charged cylinders of arbitrary diameters a1 and a2 is studiedby solvingnumerically thenonlinearPoisson-Boltzmannequation. A limit of particular interest is that of a charged cylinder interacting with a charged plane (a1 f ∞). The interaction free energy is calculated, as a function of the separation distance between the cylinders, for either fi...

| This paper compares two types of multiresolution data structure for data fusion, the data pyramid and the data cylinder. Data pyramids are well established, and in recent years non linear operators such as alternating sequential morphological lters have been used in their construction. The essential di erence between pyramids and cylinders is that pyramids undergo subsampling at each level. T...

We present an investigation into the mechanism for guidance of microstructured optical fibers consisting of high-refractive-index cylinders embedded in a low-index background. A new guidance regime is identified in which the fibers' confinement losses depend strongly on wavelength and the positions of the loss minima and maxima depend on the scattering properties of individual cylinders and onl...

During the last several decades, electromagnetic scattering from multiple cylinders has been an active research topic of in many areas, such as microwave remote sensing, theory of photonic crystals, atmospheric sciences, and so on. Rigorous theoretical treatment is therefore of critical importance. A large body of available studies in the literature concerns with two dimensional scattering, suc...

The submitted fluid dynamics videos [1] depict the various orientational dynamics of a hinged cylinder suspended in a flow tank. The different behaviors displayed by the cylinder range from steady orientation to periodic oscillation and even autorotation. We illustrate these features using a phase diagram which captures the observed phenomena as a function of Reynolds number (Re) and reduced in...

A JSJ decomposition of a group is splitting that allows one to classify all possible splittings the over certain family edge groups. Although decompositions are not unique in general, Guirardel–Levitt have constructed canonical decomposition, tree cylinders, which classifies relatively hyperbolic groups elementary subgroups. In this paper, we give new topological construction and show depends o...
