An accurate and direct measurement of the energy distribution of a low repetition rate terahertz electromagnetic pulse is challenging because of the lack of sensitive detectors in this spectral range. In this paper, we show how the total energy and energy density distribution of a terahertz electromagnetic pulse can be determined by directly measuring the absolute electric field amplitude and b...

The design, development and operation of a network for the monitoring of the nonionizing electromagnetic radiation in Greece is presented in this paper. Two independent sub-networks, called “Hermes” and “pedion24” have been operating since November 2002 in several areas, and more than 4,000,000 electric field strength measurements have been conducted to date. The measurement results indicate th...

The main goal of this study was to evaluate the possible effect of whole-body magnetic field (MF) exposure on the variations of corticosterone, Free-T3, Free-T4 and malonyl dialdehyde in plasma in 48 adult white New Zealand male rabbits. Animals were divided into six groups namely, C1 (normal diet, not exposed), C2 (normal diet, sham exposed), T1 (normal diet, exposed to electromagnetic field),...

An analytic model is proposed to estimate the electromagnetic field transmission line coupling for both radiated emission and immunity using TEM cell measurements. Further, a coupling impedance is introduced to determine the domination between electric and magnetic fields of the fieldline coupling. Comparison of measurement and calculation results confirms the accuracy of the model. The model a...

Induction sensors (also known as search coils), because of their measuring principle, are dedicated to varying magnetic field measurement. Despite the disadvantage of their size, induction magnetometer remains indispensable in numerous fields due to their sensitivity and robustness whether for natural electromagnetic waves analysis on Earth Lichtenberger et al. (2008), geophysics studies using ...

A sensor network consisting of a number of palm-sized nodes with small electric and magnetic sensors has been proposed to monitor local electromagnetic activities in space plasmas. In the present study, a compact loop antenna system is designed and fabricated for use in sensor nodes that can capture magnetic vector fields from ELF to MF frequencies. The performance of the developed system is sh...

Background and objectives: Electric, magnetic and electromagnetic fields can act as stress factors with different effects on biological systems. Due to the nutritional and medicinal values, and the increasing electromagnetic radiations, the present study was performed to investigate the effects of the electromagnetic field on the developmental stages and cytotoxic properties of...

Electromagnetic articulograph (EMA) systems are useful to study the motor control of speech articulators and also to construct models of the speech production process. In the EMA system, the position of the receiver coil is predicted on the basis of a field function representing a spatial pattern of the magnetic field in relation to the relative position between the transmitter and receiver coi...
