whereμrandεrrepresent the complex permeability (μr=μ′–jμ″) and complex permittivity (εr=ε′–jε″) respectively.f,c, andddenote the frequency of the electromagnetic wave, the speed of light in the vacuum, and the thickness of the materials, respectively. The symbol j is used ...
Moreover, the direct measurement of temperature as the energy of particles would of course be very difficult to carry out in practice. For these reasons, a conventional but convenient unit of temperature, the degree, is used in physics. It is defined as one-hundredth of the difference between...
(General Physics) a measure of the ability of a surface to radiate energy; the ratio of the radiant flux emitted per unit area to that emitted by a black body at the same temperature. Symbol:ε Collins English Dictionary – Complete and Unabridged, 12th Edition 2014 © HarperCollins Publish...

The symbol \({{{\mathcal{A}}}\) means the thermodynamic limit of \({{{\mathcal{A}}}_{L}\), while the order of the limit is always in the aforementioned one. We restrict the class of the Hamiltonians, observables, and initial states to simple ones. The Hamiltonian of the system...
Phonon polaritons are promising for infrared applications due to a strong light-matter coupling and subwavelength energy confinement they offer. Yet, the spectral narrowness of the phonon bands and difficulty to tune the phonon polariton properties hinde
Thermal conductivity (denoted by the symbol ) is a fundamental property of materials that determines their ability to conduct (i.e. transmit) heat (See Refs 1,2). Materials with a higher values conduct heat well and low- materials are more insulating (Ref 9.). ...

The energy dissipation strongly depended on the intensity of the current density. In the region with weak current (<30 nA/m2), the negative \({{{\bf{J}}}\cdot ({{{\bf{E}}}+{{{\bf{V}}}_{e}\times {{{\bf{B}}})\) means a dynamo process there. In the region with a cu...
