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 ...

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.

Numerical modelling of magnetic characteristics of ferrite core taking account of both eddy current and displacement current

Heliyon, 2019
In the magnetic field analysis of magnetic devices using a ferrite core, such as a pulse transformer, the frequency-domain analysis is often carried out using the measured complex permeability under different frequency range.

Research on the Influence of Asynchronous Coil Launcher (Coil AC Pulse Linear Motor) Shell on the Launch Efficiency

High Voltage
The effect of a metal shell on the launch efficiency of an asynchronous coil launcher (coil AC pulse linear motor) remains insufficiently understood in terms of the underlying mechanisms and principles. To address this gap, this study conducted extensive

Theory of Spacetime Impedance: A Reactive Framework for the Electromagnetic, Gravitational, and Quantum Structure of the Vacuum

Quantum Reports
This work presents the Theory of Spacetime Impedance (TSI), a phenomenological framework in which the vacuum is modeled as a distributed reactive medium with an effective RLC structure. At the classical level, the vacuum is characterized by permeability,
