Hue Change in Interference-Colored Fibers with an Alternating Multilayer Structure

Dispersion of Bloch Modes in a Multilayer Structure with Alternating Left-Handed and Right-Handed Materials

We study all-evanescent eigenmodes of a one-dimensional infinite periodic structure with alternating left-handed and right-handed materials that propagate perpendicularly to the surface or guided eigenmodes. Investigation of dispersion properties of such Bloch modes is shown to be crucial for understanding of an efficient radiation energy transport across the periodic multilayer structure. Freq...

On the Group of Alternating Colored Permutations

The group of alternating colored permutations is the natural analogue of the classical alternating group, inside the wreath product Zr ≀Sn. We present a ‘Coxeterlike’ presentation for this group and compute the length function with respect to that presentation. Then, we present this group as a covering of Z r 2 ≀ Sn and use this point of view to give another expression for the length function. ...

Multilayer Magnetic Shielding: an Innovative Overlapping Structure

The paper deals with magnetic shields for distribution systems mainly devoted to MV/LV substation. In the category of passive system, a new multilayer shielding plate is presented. The main purpose of the proposed solution is the reduction of the gap between the ferromagnetic sheets by a proper overlapping in order to reduce the local leakage fluxes. Plates characterised by different conductive...

Long Alternating Cycles in Edge-Colored Complete Graphs

Let K n denote a complete graph on n vertices whose edges are colored in an arbitrary way. And let ∆(K n) denote the maximum number of edges of the same color incident with a vertex of K n. A properly colored cycle (path) in K n, that is, a cycle (path) in which adjacent edges have distinct colors is called an alternating cycle (path). Our note is inspired by the following conjecture by B. boll...
