Earth’s magnetic field strength and atmospheric oxygen levels have oscillated in tandem for around 540 million years, according to a NASA-led study, pointing to a deep-Earth process that could knit ...

Two German physicists have unveiled a compact magnet layout that outperforms the famed Halbach array, delivering stronger, ...

Abstract: A decoupling method for magnetic dipole antenna array based on mu-near-zero (MNZ) metamaterials is proposed in this paper. A small loop antenna with a circumference of 0.085λ 0 is used as an ...

Earth’s magnetic field has correlated with fluctuations in atmospheric oxygen, according to a newly released study.

The transient field-frequency domain of magnetic dipole in a two-layered conducting Earth has been studied. It is obtained as a summation of waveguide modes plus contributions from branch cuts in the ...
