SHIFT OF ANTIPODE MAXIMUM OF ELECTRIC FIELD IN THE RESONATOR THE EARTH–IONOSPHERE CAVITY CAUSED BY DAY–NIGHT NON-UNIFORMITY [PDF]

open access: yesРадиофизика и электроника, 2017
Accounting for the actual structure of the lower ionosphere in the problems of global electromagnetic (Schumann) resonance is an important and urgent task.

Anthropogenic Noise and Its Footprint on ELF Schumann Resonance Recordings

open access: yesFrontiers in Earth Science, 2021
A set of various short artificial disturbances from rifle firings, car engine operation, car radio, shakings of the apparatus, etc., were generated deliberately near our ELF recording stations in order to identify their footprint on the recordings of ...

Integrated Schumann Resonance Intensity as an Indicator of the Global Thunderstorm Activity

open access: yesGeosciences, 2023
This paper addresses the accuracy of estimates for the contemporary level of global thunderstorm activity found from the synchronous records of integrated Schumann resonance (SR) intensity at two high-latitude observatories in the Northern and Southern ...

Schumann resonance transients and the search for gravitational waves

open access: yes, 2018
Schumann resonance transients which propagate around the globe can potentially generate a correlated background in widely separated gravitational wave detectors. We show that due to the distribution of lightning hotspots around the globe these transients

Laser-produced continua for absorption spectroscopy in the VUV and XUV [PDF]

open access: yes, 1980
Recent work has shown that with appropriate targets, laser-produced plasmas provide clean essentially linefree continua suitable for absorption spectroscopy from 40 to 2000 Å.

Schumann’s resonances: A particular example of a spherical resonant cavity

open access: yesAmerican Journal of Physics, 2004
The resonances between the Earth as one boundary and the ionosphere as the other, known as Schumann’s resonances, represent an interesting example of a spherical cavity. We consider a simple model in which the boundaries behave as perfect conductors and then take into account the finite conductivity of the boundaries. Numerical results are obtained for
