Wave guidance is an important aspect of light trapping in thin film photovoltaics making it important to properly model the effects of loss on the field profiles. This paper derives the full-field solution for electromagnetic wave propagation in a symmetric dielectric slab with finite absorption. The functional form of the eigenvalue equation is identical to the lossless case except the propaga...

A key feature of subduction zone geodynamics and thermal structure is the point at which slab mantle mechanically couple. This defines depth traction between begins to drive wedge circulation also corresponds with a rapid increase in temperature along slab-mantle interface. Here, we consider effects backarc parameter on coupling using two-dimensional thermomechanical models oceanic-continental ...

Robust and accurate control of secondary cooling is vital to the successful operation of any caster and the production of high quality products. This is especially important in thin slab casters, because high casting speed and a tight machine radius often requires carefully-prescribed temperature profiles to avoid various cracking problems. This can be achieved only by successful control of the...

In the flat products steel industry, the hot rolling mill transforms the incoming slabs in a thin coil which then can be processed to obtain the final products. Thickness is reduced by pulling the plate between two parallel rolls while moving the upper work roll. The effect of uneven thickness at both sides can produce deviations in the longitudinal direction of the slab, which have to be manua...

The propagation and transmission of Bessel beams through nano-layered structures has been discussed recently. Within this framework we recognize the formation of unguided diffraction-free waves with the spot size approaching and occasionally surpassing the limit of a wavelength when a Bessel beam of any order n is launched onto a thin material slab with grazing incidence. On the basis of the pl...

A 62-year-old man with chronic myelomonocytic leukaemia presented increasing dyspnoea one month after a pericardiocentesis. Chest MDCT scan (Figs. 1 and 2) showed left ventricle pouching of contrast material, suggestive of pseudoaneurysm (probably iatrogenic), confirmed with trans-thoracic echo-cardiogram (Video 1). Surgical repair successfully closed the ventricle-pseudoa-neurysm connection. F...

Finite-thickness slabs of hyperbolic media with tilted optical axes exhibit asymmetry properties for waves propagating upward and downward with respect to slab interfaces. Under certain conditions, asymmetric hyperbolic media acquire extreme permittivity parameters and the difference between upward and downward propagating waves becomes very large. Furthermore, both waves can be perfectly match...

We discuss plasmonic excitations in a thin slab of topological insulators. In the limit of no hybridization of the surface states and same electronic density of the two layers, the electrostatic coupling between the top and bottom layers leads to optical and acoustic plasmons which are purely charge and spin collective oscillations. We then argue that a recent experiment on the plasmonic excita...
