The ponderomotive and reaction forces are defined by the time derivatives of the medium and electromagnetic pseudomomenta, which depend on the "hidden momentum" in the case of a magnetoelectric medium. Properties of medium-field interaction are connected with translational invariance of the pseudo...
State true or false: Electromagnetic forces are one of the fundamental forces. True. Q3 How electromagnetic radiation occurs? Electromagnetic radiation occurs when an atomic particle, like an electron, is accelerated by an electric field, causing it to accelerate. ...
In this program the Lorentz forces are generated by a series of “acceleration cells” made up of azimuthally spaced conductor arrays that are excited by the discharge of small condenser banks. These banks are used repetitively during the acceleration process by recharging them from a “master ...
which is observed with zero stirring and at the minimum undercooling required to access the metastable phase (and thus minimum driving force) as defined by the phase diagram. This condition is indicated in Fig.3bas an orange star. The observed slope of the dimensionless log-log plot is negativ...
Thus the applied electric field produces only a very small separation of the charged particles if these are bound together by strong atomic forces. But the same field produces a larger separation of the charged particles if these are bound together by weaker atomic forces. In the following, two...
the laser ablation process to modify the surface of titanium, thus obtaining the beneficial properties of its surface; the effects included the increase in the real area of the contact surface, whose chemical composition was furthermore changed consequently improving the wettability and adhesion forces...
(1) and (2), the ϑ-parameter is defined by ϑ=κ74L(ℓPL)ΥfℓP2. (51) In Ref. [32], it is argued that Υf=−1 and κ7=37.5 for neutrinos. Here, it is necessary to carry on a similar analysis to determine the values of these parameters, when dealing with ...
The electromagnetic field (EMF) is a type of physical field where external forces generated by electrically-charged objects are present. The EMF travels through space in the form of electromagnetic waves (radiation), which consist of two coupled elements: magnetic and electric fields. The speed o...
To recover the unit cell to its original configuration, a pair of compressive forces needs to be applied to the unit cell to enable it snap back to the close state. Tessellating the unit cell in both horizontal and vertical directions creates a metasurface. Figure 1b shows an example ...
A dielectric dimer, depending on the embedding medium, can display either repulsive or attractive forces53. A perfect switch of the scattering direction based on a dielectric sphere dimer has been also proposed54. Electric and magnetic modes in dielectric dimers have been directly measured by ...
