Experiment regarding magnetic fields with gravity
IET Quantum Communication, Volume 3, Issue 4, Page 218-228, December 2022., 2022 Abstract This experiment was designed to test the string theory as a physical reality. The ground‐based device placed the N poles of the magnets upwards, north, south, east, and west. Coil Ass'Y was placed between 2 N poles with bearing covers on the top and bottom.

THE FRACTAL NATURE OF THE ELECTROMAGNETIC FIELD WITHIN A REVERBERATING CHAMBER [PDF]
Progress In Electromagnetics Research C, 2012 In this paper, a new look at the electromagnetic fleld in a reverberating chamber (RC) is presented. It follows the fractional Brownian motion (fBm) model and exploits the Hurst parameter as the key parameter to discriminate among various RC conflgurations.

Measurement of Absorption Cross Section of a Lossy Object in Reverberation Chamber Without the Need for Calibration [PDF]
, 2016 A reliable and simple procedure is proposed to measure the averaged absorption cross section (ACS) of a lossy object in a reverberation chamber (RC). This procedure is based on the time-domain measurement of the ACS in an RC.

Uncorrelated Configurations and Field Uniformity in Reverberation Chambers Stirred by Tunable Metasurfaces [PDF]
Appl. Phys. Lett. 118, 144101 (2021), 2019 Reverberation chambers are currently used to test electromagnetic compatibility as well as to characterize antenna efficiency, wireless devices, and MIMO systems. The related measurements are based on statistical averages and their fluctuations. We introduce a very efficient mode stirring process based on electronically reconfigurable metasurfaces ...

Diffuse field cross-correlations: scattering theory and electromagnetic experiments [PDF]
, 2021 The passive estimation of impulse responses from ambient noise correlations arouses increasing interest in seismology, acoustics, optics and electromagnetism. Assuming the equipartition of the noise field, the cross-correlation function measured with non-invasive receiving probes converges towards the difference of the causal and anti-causal Green's ...

Radiated Immunity Testing of a Device with an External Wire: Repeatibility of Reverberation Chamber Results and Correlation with Anechoic Chamber Results [PDF]
, 2003 We present the experimental radiated immunity results of an electronic device with an external wire obtained in reverberation and anechoic chambers. Repeatability and reproducibility of reverberation chamber measurements are investigated by repeating the
