Laboratory observation of nonlocal dispersion

Transport in Porous Media, 1996
This work presents the results of a one-dimensional experimental investigation of contaminant transport in heterogeneous porous media. The usual transport equations fail to adequately predict dispersion in such systems, and new theories to account for the distinctions have not yet been examined experimentally.

Dynamics of a Nonlocal Dispersal Model with a Nonlocal Reaction Term

International Journal of Bifurcation and Chaos, 2018
In this paper, we study a class of nonlocal dispersal problem with a nonlocal term arising in population dynamics: [Formula: see text] where [Formula: see text] is a bounded domain, [Formula: see text], [Formula: see text] represents the nonlocal dispersal operator with continuous and non-negative dispersal kernel.

Nonlocality in the Two-Dimensional Plasmon Dispersion

Physical Review Letters, 1985
Two-dimensional plasmons have been investigated in AlGaAs-GaAs heterostructures with transmission spectroscopy. In a magnetic field $B$, we observe an interaction of the plasmon excitation with harmonics of the cyclotron-resonance frequency ${\ensuremath{\omega}}_{c}=\frac{\mathrm{eB}}{m}$, which arises from nonlocal effects on the two-dimensional ...

Nonlocal cancellation of dispersion

Optical Society of America Annual Meeting, 1991
Two classical, coincident light pulses propagating through two different dispersive media will become broadened and their degree of coincidence will be reduced. The width of the coincidence curve can be shown to be proportional to ( β 1 2 + β 2 2 ) x

Nonlocal models for nonlinear, dispersive waves

Physica D: Nonlinear Phenomena, 1989
The authors discuss nonlocal models for nonlinear dispersive waves. It is shown that the initial value problem for these equations is globally well posed in the classical sense. The result of the problem is stated for specific equations but the techniques utilized are shown to be used for a wide range of problems. The paper is of theoretical nature; it

Nonlocal transformation optics for dispersion engineering

2015 9th International Congress on Advanced Electromagnetic Materials in Microwaves and Optics (METAMATERIALS), 2015
We explore possible applications of our previously-introduced nonlocal-transformation-optics framework to scenarios of interest for dispersion engineering. In particular, we address the design of nonreciprocal effects (such as unidirectional propagation), as well as exotic effects such as the “frozen-mode” regime and Dirac-cone-type dispersion.
