Electric and magnetic field measurements were taken in the extremely low frequency (ELF), very low frequency (VLF), and radio frequency (RF) ranges of the EM spectrum. In 2 rooms, ELF electric fields were reduced and VLF and RF electric fields were increased as a result of the changeover ...
The electromagnetic fields radiated from a loop antenna on which an oscillating current flows across the static magnetic field B0 are calculated in several simple geometries by the finite element method (FEM) and by analytical methods in a cross section of a plasma cylinder. The wave number along...
In recent years there has been a significant increase in the use of radio telephones and other RF emitting devices operating at frequencies between 0,8 GHz and 6 GHz. Many of these services use modulation techniques with a non-constant envelope (e.g. TDMA). In addition to electromagnetic ene...
