Resonance Properties of Optical All-Dielectric Metamaterials Using Two-Dimensional Multipole Expansion [PDF]

open access: yes, 2012
We examine the electromagnetic response of metamaterial unit elements consisting of dielectric rods embedded in a non-magnetic background medium. We establish a theoretical framework where the response is described through the electric and magnetic ...

Theoretical evaluation of radio noise and audible noise in transmission lines

open access: yesRevista Facultad de Ingeniería Universidad de Antioquia, 2005
One of the most important effects in transmission lines (TL) is the corona effect, which is the cause of related phenomena like radio noise (RN) and audible noise (AN).

Comment on "Role of Potentials in the Aharonov-Bohm Effect" [PDF]

open access: yes, 2015
Are the electromagnetic scalar and vector potentials dispensable? Lev Vaidman has suggested that local interactions of gauge-invariant quantities, e.g. magnetic torques, suffice for the description of all quantum electromagnetic phenomena. We analyze six

Analysis of magnetohydrodynamic phenomena in a single spatial electromagnetic field [PDF]

open access: yesE3S Web of Conferences
The paper presents the results of the analysis of the disinfection of water by a pulsed single spatial electromagnetic field. The origin of the fluid pressure in the pipe is calculated and graphically presented as the interaction of a single spatial ...
