We apply these coefficients to the special case of a charged particle placed at the origin of S, the accelerated system. The electromagnetic field, a six-vector, will be transformed according to Let the field of the charge in S be Coulombian, that is,....
During the latter part of the 19th century, an entirely new line of reasoning developed that derived, in great part, from James Clerk Maxwell's prediction of the velocity of an electromagnetic wave from first principles, and the development of his famous equation that stated the speed of an ...
Light has been harnessed for hundreds of years for applications ranging from microscopy to astronomy. The full vectorial nature of electromagnetic radiation, however, has a far shorter history and its use for imaging and sensing is still largely unexplored. Of particular interest are light beams ...
This article presents properties of the Earth's magnetic field and its impact on the commercial flight navigation. Scientific studies of the Earth's magnetic field in Slovenia during the last thirty years are presented. This paper deals with theoretical research regarding the magnetopause that protect...
Indeed, the absorption and emission of radiation by a material structure contributes to reach thermal equilibrium with other surrounding structures and the electromagnetic environment. This is the dominant cooling channel for thermally isolated structures8, in which energy is released through the emission ...
Thermal nanophotonics has undergone a revolution in recent decades, benefiting from in-depth studies in nano-optics and breakthroughs in nanotechnologies. The majority of thermal devices are constrained by Kirchhoff’s law of thermal radiation, whereby spectral directional absorptivity and emissivity are id...

Bursts of electromagnetic radiation that share similarities with birdsong have long been observed close to Earth. A detection farther out in space confirms a key part of the theory of their origin, but also poses questions. Richard B. Horne ...
Mid-infrared photonics is the practical application of electromagnetic radiation with a wavelength between two and approximately twenty micrometres. This region includes a number of so-called water windows: wavelengths of light that can propagate through the Earth’s atmosphere without being absorbed by...
“hot structures” that lower the thermal load through both environmental radiation and conduction into the vehicle (e.g., nose of the X-51 cruiser). Examples of these appear in Fig.1g, i. Semi-passive systems are implemented for high heat fluxes that persist for long durations, and ...
