Reflectionless anisotropic multilayers for both polarisations at grazing incidence

open access: yesEPJ Applied Metamaterials, 2022
We find a method for designing anisotropic multilayer profiles that are reflectionless at grazing incidence, for both electromagnetic polarisations.

Isotropization of the universe during inflation [PDF]

open access: yes, 2015
A primordial inflationary phase allows one to erase any possible anisotropic expansion thanks to the cosmic no-hair theorem. If there is no global anisotropic stress, then the anisotropic expansion rate tends to decrease.

Resonant Anisotropic (p,q)-Equations [PDF]

open access: yesMathematics, 2020
We consider an anisotropic Dirichlet problem which is driven by the (p(z),q(z))-Laplacian (that is, the sum of a p(z)-Laplacian and a q(z)-Laplacian), The reaction (source) term, is a Carathéodory function which asymptotically as x±∞ can be resonant with respect to the principal eigenvalue of (−Δp(z),W01,p(z)(Ω)).

On solutions of anisotropic elliptic equations with variable exponent and measure data [PDF]

open access: yesComplex Variables and Elliptic Equations, 2018
The Dirichlet problem in arbitrary domains for a wide class of anisotropic elliptic equations of the second order with variable exponent nonlinearities and the right-hand side as a measure is considered.

SURFACE EFFECT DUE TO INCIDENT PLANE SURFACE HORIZONTAL WAVES

open access: yesInternational Islamic University Malaysia Engineering Journal, 2012
Surface effect due to incident plane surface horizontal waves through anisotropic elastic materials is studied. Mathematical formulation over the modeled earth's alluvial valley is transformed into integral equations.

Kinetic description of mixtures of anisotropic fluids

open access: yes, 2014
A simple system of coupled kinetic equations for quark and gluon anisotropic systems is solved numerically. The solutions are compared with the predictions of the anisotropic hydrodynamics describing a mixture of anisotropic fluids.

Nonlinear evolution equations for degenerate transverse waves in anisotropic elastic solids

open access: yes, 2008
Transverse elastic waves behave differently in nonlinear isotropic and anisotropic media. Quadratically nonlinear coupling in the evolution equations for wave amplitudes is not possible in isotropic solids, but such a coupling may occur for certain ...

Existence and regularity for critical anisotropic equations with critical directions

open access: yesAdvances in Differential Equations, 2011
We establish existence and regularity results for doubly critical anisotropic equations in domains of the Euclidean space. In particular, we answer a question posed by Fragalà–Gazzola–Kawohl [24] when the maximum of the anisotropic configuration ...
