The quasilinear scattering mean free path of solar flare electrons and nucleons is calculated for interplanetary plasma wave turbulence consisting of a mixture of slab shear Alfvén waves and isotropic fast magnetosonic waves. It is shown that for well-sampled electron and nucleon mean free paths over a wide and overlapping energy range the underlying frequency power spectra of left-handed and r...

The complete phononic band gap (PnBG) of a phononic crystal (PnC) slab is used to efficiently and simultaneously confine both flexural and extensional (longitudinal) elastic vibrations in a resonator. The PnC structure is fabricated by etching a hexagonal (honeycomb) array of air holes in a silicon (Si) slab. Flexural and extensional acoustic modes in the structure are directly excited by a pie...

A backward-wave slab based on a capacitively and inductively loaded three-dimensional transmission-line network is designed in such a way that impedance-matching with free space is obtained. To enable field propagation from free space to the network and vice versa, the use of a transition layer is proposed. Matching of the designed network with free space and negative refraction occurring at th...

We present a calculation of the change of free energy of a solid surface upon bending of the solid. It is based on extracting the surface stress through a molecular dynamics simulation of a bent slab by using a generalized stress theorem formula, and subsequent integration of the stress with respect to strain as a function of

Empirical evidence gathered at the onset of ablation on a ski slope where a wet slab avalanche claimed the life of a skier indicates a chance of snowpack fracture. Wetting fronts which fully penetrate the basal layer of depth hoar in response to the first episode of excessive diurnal melt result in a softening of ice-to-ice contact points and a significant change in cup-shaped ice particle geom...

We demonstrated a construction of negative-index material (NIM) with epsilon(eff)=mu(eff)=-1 employing ferrites only, with no metallic components. Our design of the NIM is motivated by recent coherent potential approximation results and corroborated by exact numerical calculation demonstrating the negative refraction of an electromagnetic beam, with equal incident and refraction angles, as well...

This study presents the results of an experimental program to investigate the effectiveness of an innovative combined FRP technique using combination of externally bonded (EB) FRP fabrics and near surface mounted (NSM) FRP rods for flexural strengthening of existing reinforced concrete (RC) two-wayslabs with low clear cover thickness. Three full-scale RC slabs (1500×1500×120 mm) were tested und...

For a stationary nonlinear Boltzmann equation in a slab with a particular truncation in the collision operator, the Milne problem for the boundary layer together with a weak type of hydrodynamic behaviour in the interior of the slab, are studied by non-perturbative methods in the small mean free path limit.
