Near field evidence of backward surface plasmon polaritons on negative index material boundaries
(Elsevier Science, 2016-12)
We present a detailed analysis about the electromagnetic response of a metamaterial surface with a localized defect. The excitation of electromagnetic surface waves leads to a near-field distribution showing a periodic ...
Ion-acoustic waves triggered by left-hand polarized finite-amplitude waves propagating in the beam direction
(Blackwell Publishing Ltd, 2006)
Nonlinear ion-acoustic like waves triggered by large-amplitude circularly polarized waves propagating in the direction of a proton beam are studied. The properties are strongly dependent on the nature of the large-amplitude ...
Nonlinear electrostatic instabilities in the solar wind
(Blackwell Publishing Ltd, 2009)
It is well known that nonlinear electrostatic instabilities can be triggered in a plasma with streaming ion species in the presence of finite-amplitude Alfvén cyclotron waves. The instability occurs when the phase velocity ...
Nonlinear Electrostatic Ion-Acoustic-Like Instabilities in a System with Two Streaming Ion Components Moving in a Background Plasma
(Bentham open, 2008-11-26)
Finite amplitude Alfvén-cyclotron waves are believed to play an important role in coronal heating and
nonthermal properties of velocity distribution functions. These effects are thought to be due to parametrically ...
Nonlinear ion-acoustic waves supported by an ion beam
(2007)
It is shown that in a plasma composed by electrons, a proton core, and a proton beam propagating along an external magnetic field, finite amplitude left-hand polarized waves propagating backward relative to the beam direction ...
Electrostatic ion-acoustic-like instabilities in the solar wind with a backstreaming alpha particle beam
(2010)
Nonlinear electrostatic instabilities have been shown to occur frequently and under very different conditions in plasma with two ion beams such as the fast solar wind. These instabilities can be triggered when the phase ...
High Wave Activity Observed in Patagonia, Southern America: Generation by a Cyclone Passage over Andes Mountain Range
(Wiley, 2013-01)
The Antarctic peninsula and Patagonia region (South of South America) have recently been identified as one of the regions with the highest gravity wave activity in the world. In this work, the generation and propagation ...
High gravity-wave activity observed in Patagonia, Southern America: generation by a cyclone passage over the Andes mountain range
(Wiley, 2012-07)
The Antarctic peninsula and Patagonia region (the south of South America) have recently been identified as the regions with the highest gravity-wave activity in the world. In this work, the generation and propagation of ...
Radiation characteristics of electromagnetic eigenmodes at the corrugated interface of a left-handed material
(American Physical Society, 2009-08)
We study the radiation characteristics of electromagnetic surface waves at a periodically corrugated interface between a conventional and a negatively refracting (or left-handed) material. In this case, and contrary to the ...
Interpolating quantum electrodynamics between instant and front forms
(2018-08-01)
The instant form and the front form of relativistic dynamics proposed by Dirac in 1949 can be linked by an interpolation angle parameter δ spanning between the instant form dynamics (IFD) at δ=0 and the front form dynamics, ...
