We calculate the optical attractive forces that occur between 30-nm Au or Ag nanocrystals when irradiated at visible wavelengths. These forces show resonances at dipolar plasmon wavelengths, similar to resonances in the near-field electromagnetic intensities. At MW/cm2 intensities, optical forces can be stronger than van der Waals forces and could be used to organize metallic particles. We also...

Electromagnetic designs are found in a wide variety of industrial and R&D applications: cables, magnetic shielding, transmission lines, high voltage systems, and other EM systems. Engineers need to understand the electromagnetic behaviors (e.g. fields, forces, eddy currents, etc.) of these designs so that costs and performance can be effectively managed. In the past, engineers were limited to c...

We have implemented field models and performed a detailed numerical dosimetry inside our extremely-low-frequency electromagnetic bioreactor which has been successfully used in in vitro Biotechnology and Tissue Engineering researches. The numerical dosimetry permitted to map the magnetic induction field (maximum module equal to about 3.3 mT) and to discuss its biological effects in terms of indu...

Material forces govern the behaviour and the evolution of a defect or of an inhomogeneity in a solid material. In elastic materials these forces are associated with the Eshelby tensor, as is known. In structured or micro-structured materials, an Eshelby–like stress can be assembled by following a simple rule. By appealing to this rule, one is able to propose an expression for the Eshelby tensor...

Interactions between galactic cosmic rays and matter are a primary focus of the NASA radiation problem. The electromagnetic forces involved are for the most part well documented. Building on previous research, this study investigated the relative importance of the weak forces that occur when a cosmic ray impinges on di!erent types of materials. For the familiar electromagnetic case, it is known...

In this paper, the effectiveness of electromagnetic forces on controlling motion a sedimenting elliptical particle is investigated using immersed interface-lattice Boltzmann method (II-LBM) in which signed distance function adopted to apply jump conditions for II-LBM and add external forces. First, mechanisms control suppressing vorticity generation based equation vortex shedding streamwise mom...

Mechanical and electromagnetic relations involved in the Trouton–Noble paradox are analysed on the basis of special relativity theory as well as on the basis of Maxwellian electrodynamics. It is shown that the paradox only arises when not all dynamical effects associated with the moving capacitor used by Trouton and Noble are considered. Crucial for the resolution of the paradox is the fact tha...
