Signal discrimination of ULF electromagnetic data with using singular spectrum analysis – an attempt to detect train noise [PDF]

open access: yesNatural Hazards and Earth System Sciences, 2011
Electromagnetic phenomena associated with crustal activities have been reported in a wide frequency range (DC-HF). In particular, ULF electromagnetic phenomena are the most promising among them because of the deeper skin depth.

Resonant absorption and amplification of circularly-polarized waves in inhomogeneous chiral media

open access: yes, 2016
It has been found that in the media where the dielectric permittivity $\epsilon$ or the magnetic permeability $\mu$ is near zero and in transition metamaterials where $\epsilon$ or $\mu$ changes from positive to negative values, there occur a strong ...

Nonlinear propagation of broadband intense electromagnetic waves in an electron-positron plasma [PDF]

open access: yes, 2006
A kinetic equation describing the nonlinear evolution of intense electromagnetic pulses in electron-positron (e-p) plasmas is presented. The modulational instability is analyzed for a relativistically intense partially coherent pulse, and it is found ...

Superconducting Phenomena and Electromagnetism III

open access: yesTEION KOGAKU (Journal of Cryogenics and Superconductivity Society of Japan), 2011
One hundred years have passed since the discovery of superconductivity. Over this time, the science, especially in the area of physics, relating to superconductivity has improved dramatically. However, no appreciable progress has been made in the education of superconductivity in relation to primary electromagnetism.
