TORSION AND THE ELECTROMAGNETIC FIELD [PDF]
International Journal of Modern Physics D, 1999 In the framework of the teleparallel equivalent of general relativity, we study the dynamics of a gravitationally coupled electromagnetic field. It is shown that the electromagnetic field is able not only to couple to torsion, but also, through its energy–momentum tensor, produce torsion.

ELECTROMAGNETIC FIELDS ON FRACTALS [PDF]
Modern Physics Letters A, 2006 Fractals are measurable metric sets with non-integer Hausdorff dimensions. If electric and magnetic fields are defined on fractal and do not exist outside of fractal in Euclidean space, then we can use the fractional generalization of the integral Maxwell equations. The fractional integrals are considered as approximations of integrals on fractals. We

Controlling Electromagnetic Fields
Science, 2006 Using the freedom of design that metamaterials provide, we show how electromagnetic fields can be redirected at will and propose a design strategy. The conserved fields—electric displacement field D , magnetic induction field B , and Poynting vector B —are all ...

Measurement of rotational magnetic properties of nanocrystalline alloys by a modified B-H sensor
AIP Advances, 2017 Nanocrystalline alloys are now widely used in high frequency electromagnetic applications such as high frequency transformers and chokes, while it’s two-dimensional properties are seldom investigated.

Invariants of the electromagnetic field [PDF]
Journal of Mathematical Physics, 2014 We present a constructive proof that, in electrodynamics, all of the gauge-invariant Lorentz scalars and pseudoscalars can be expressed as functions of the quadratic ones.

Influence of Mutual Coupling on Stability of RCS Response in Chipless RFID
Technologies, 2018 The paper investigates the influence of mutual coupling between individual scatterings of chipless Radio Frequency Identification (RFID) tags based on its frequency-domain performance using a simplified equivalent circuit model. The proposed steady state

A comparision of Hodgkin-Huxley and soliton neural theories [PDF]
Advances in Radio Science, 2010 Hodgkin and Huxley were the pioneers to abstract biological neuron as an electric circuit and nerve signal as the voltage impulse. The Hodgkin-Huxley theory (Hodgkin and Huxley, 1952) has set the direction and defined the goals for much of the ensuing ...

Generation of Electromagnetic Field by Microtubules [PDF]
International Journal of Molecular Sciences, 2021 The general mechanism of controlling, information and organization in biological systems is based on the internal coherent electromagnetic field. The electromagnetic field is supposed to be generated by microtubules composed of identical tubulin heterodimers with periodic organization and containing electric dipoles.

Reactor vibration reduction based on giant magnetostrictive materials
AIP Advances, 2017 The vibration of reactors not only produces noise pollution, but also affects the safe operation of reactors. Giant magnetostrictive materials can generate huge expansion and shrinkage deformation in a magnetic field.
