in this paper are present the results of measurements of magnetic induction at some locationsin city bor (the east serbia) dating from the household electric devices and transformer stations suited near the residental areas. stress is on the extremely low frequent electromagnetic radiation from transformer stations and other high voltage instalations in urban areas. risk of the extremely low fr...

− The paper deals with a fast measurement technique of electromagnetic transients due to eddy currents in fast-cycled magnets for linear particle accelerators. First the context of the problem, related to the need for accurate control of the magnetic field quality in order to ensure the stability and performance of the particle beam in dynamic conditions (field ramps up to about 700 T/s) is out...

As a result of dense installations of public mobile base station, additional electromagnetic radiation occurs in the living environment. In order to determine the level of radio-frequency radiation generated by base stations, extensive electromagnetic field strength measurements were carried out for 664 base station locations. Base station locations were classified into three categories: indoor...

Given the recent direct measurement of gravitational waves (GWs) by the LIGO-VIRGO collaboration, the coupling between electromagnetic fields and gravity have a special relevance since it opens new perspectives for future GW detectors and also potentially provides information on the physics of highly energetic GW sources. We explore such couplings using the field equations of electrodynamics on...

The research report presents the chip-scale solutions for THz spectroscopy applications. On the transmitter side, the architecture achieves dynamic waveform shaping of THz periodic waveform in free space by allowing interference of radiated electromagnetic-fields with rich harmonic components and proper delays at far field. On the receiver side, the electromagnetic interface between the on-chip...

The ability of the electromagnetic flux measured in various locations of a 35-kW cage induction motor to provide useful information about faults was investigated. The usefulness of this monitoring parameter was assessed in comparison with some other electrical parameters used for fault detection, such as stator phase current and circulating currents between the parallel branches of the stator w...

We consider the inverse electromagnetic scattering problem of determining the shape of a perfectly conducting cavity from measurement of scattered electric field due to electric dipole sources on a surface inside the cavity. We prove a reciprocity relation for the scattered electric field and a uniqueness theorem for the inverse problem. Then the near field linear sampling method is employed to...

Abstrac t-The results of a magnetic and electromagnetic measurement survey are presented, which was carried out around a Magnetic Resonance Imaging device. The investigation is performed with the twofold aim of characterising the field source under the different operating sequences and evaluating the exposure of workers both to the static and time-varying magnetic field. The exposure levels are...
