Modeling of the spectrum of the seismo-electromagnetic and acoustic waves, caused by seismic and volcanic activity, has been done. This spectrum includes the Electromagnetic Emission (EME, due to fracturing piezoelectrics in rocks) and the Acoustic Emission (AE, caused by the excitation and the ...
These signals are analyzed in real time and their power spectrum contents and time/frequency data are available online. To date, specific interest has been devoted to searching for any possible electromagnetic features which correlate with seismic activity in the same region. In this study, spectral...
the criteria that its spectral power had to be larger than the pre-ictal spectrum and only the single most powerful lobe in the spectrum was selected (basically side-lobes of the ictal spectrum were rejected even if significantly larger than pre-ictal spectrum to ensure a narrow-band selection...

Radiofrequency electromagnetic radiation (RFR), a form of energy between 10 KHz-300 GHz in the electromagnetic spectrum, is used in wireless communication and emitted from antennae of mobile telephones (handys) and from cellular masts. RFR can penetrate into organic tissues and be absorbed and conv...
Currently, technology is being developed that makes use of the millimeter wave (MMW) range (30-300 GHz) of the radio frequency region of the electromagnetic spectrum. As more and more systems come on line and are used in everyday applications, the possibility of inadvertent exposure of personne...
Therefore, the resulting power spectrum is the sum of individual power spectra of particular strokes. In fact, the global thunderstorm activity covers substantial areas and moves around the globe during the day. These features will play an important role when comparing observations with model data. ...
The dielectric properties of various organs and tissues in living bodies have been previously characterized over a wide spectrum29,30. The resonance frequency of proposed EM-based implant sensor depends on permittivity of the surrounding environment. The sensor frequency changes inversely with changes in...
This is extremely important for the efficient use of the spectrum. Multiband antennas are better technological solutions to arrive at this objective while reducing the dimensions of the R.F. front-end. Every antenna typically operates in two or one frequency band, and different antennas are needed...
