TL;DR: In this article, the effect of multi-path fading in free-space communications between antenna arrays capable of generating OAM states was investigated, where the authors assumed that the electromagnetic field fluctuations driving the multihop fading are statistically equivalent to those produced by multiple reflections and scattering within a cavity with irregular geometry and distributed wall losses.

TL;DR: In this article, the parametric decay instability of a large amplitude extraordinary pump wave into a whistler wave and a backscattered extraordinary wave was investigated by computer simulation, and it was shown that such a wave can be transformed into a back-scattered wave.

TL;DR: Coupled chaotic oscillators that display extreme events are studied to show that it is possible to forecast in real time an impending extreme event and that extreme events can be suppressed by applying tiny perturbations to the system.

TL;DR: In this paper, an extension of the previously developed Random Coupling Model statistical description of wave coupling into enclosures to describe the coupling through apertures, coupling to mixed systems for which only part of the ray phase space is chaotic, and coupling to systems of systems in which the components have varying degrees of isolation, for example chains of cavities.

TL;DR: In this article, it was shown that a large class of phase oscillator models admit low dimensional descriptions for the macroscopic system dynamics in the limit of an infinite number N of oscillators.
