In-depth experimental search for a coupling between gravity and electromagnetism with steady fields [PDF]

Scientific Reports
Any means to control gravity like electromagnetism is currently out of reach by many orders of magnitude even under extreme laboratory conditions. Some often poorly executed experiments or pseudoscience theories appear from time to time claiming for ...

Electromagnetic Wave Propagation in Media with Indefinite Permittivity and Permeability Tensors [PDF]

Physical Review Letters, 2003
We study the behavior of wave propagation in materials for which not all of the principle elements of the permeability and permittivity tensors have the same sign. We find that a wide variety of effects can be realized in such media, including negative refraction, near-field focusing and high impedance surface reflection.

Effect of electromagnetic permeability on transition temperature of superconductivity [PDF]

International Journal of Modern Physics B, 2017
The description of superconductivity at high-temperature is a problem that has recently been addressed. Transition temperature of superconductivity, [Formula: see text], depends on the lattice structure type, size and room pressure. In super-lattices and low-dimensional layered nanostructures, [Formula: see text] is increased by increasing the ...

Determination of dielectric permeability of substances by electromagnetic waveguide method

Journal of Physics and Electronics, 2020
A method for determining the complex permittivity of substances by the electromagnetic (EM) waveguide method in the microwave range using electrodynamics and the theory of multilayer dielectric structures is considered. The expression for the complex reflection coefficient of an EM wave in a waveguide with a substance sample is studied. Calculations of

Electromagnetic field induced permeability response of cells and membranes

Effects of man-made electromagnetic fields on living organisms potentially include transient and permanent changes in cell behaviour, physiology and morphology. At present these effects are poorly defined, yet their understanding may provide important insights.

Negative index materials: at the frontier of macroscopic electromagnetism

Comptes Rendus. Physique, 2020
The notions of negative refraction and negative index, introduced by V. Veselago more than 50 years ago, have appeared beyond the frontiers of macroscopic electromagnetism and purely formal during 30 years, until the work of J.
