This paper will review the models behind the interaction processes experienced by detectors sensing radio, visible and gamma-ray signals arid analyze why the conclusions about the nature of EM-waves should necessarily appear to be different and contradictory. The physical interaction processes between ...

Electrically driven amplification of terahertz acoustic waves in graphene Electron–phonon interactions are a crucial aspect of high-quality graphene devices. Here, the authors show that graphene resistivity grows strongly in the direction of the carrier flow when the drift velocity exceeds the speed of...
Yan et al.11 proposed a finite-difference time-domain (FDTD) algorithm to estimate the coupling of external EM waves (1.5–6 GHz) to TP cables. In this reference, it is observed that the interference is maximum when the wavelength is half-integer or integer multiple of the twist pitch ...
a jet in the northern polar region and waves involving the magnetic field. In this Review, we explore the dynamics of core gyres, jets and waves and discuss their impact on the magnetism and rotation of the Earth. The planetary gyre is anticyclonic, offset from the rotation axis towards low...

(PL), λem≅503 nm, at room temperature under continuous-wave excitation, λexc = 405 nm. Numerical simulations confirm that the observed improvement in emission is a result of a multiscale light enhancement owing to the ensemble of QD-populated plasmonic nanocavities in the material...
Inside the cavity is an antenna that shines radio waves throughout therefore turning the gas into highly charged plasma (3-5 million degrees), similar to lightening bolts in thunderstorms. A magnetic field directs the charged plasma to the smaller rear nozzle or cone of the engine creating a ...
