Background: This study aims to evaluate the negative health impacts of exposure to electromagnetic field and to prepare a risk map of two selected call centers. Materials and Methods: Two call centers whose electromagnetic field values were measured by calibrated low high and point frequency measurement device. The measurements were performed by following the EN 50492 Standards. 178 employees ...

To measure electromagnetic fields accurately, the calibration of field probes is necessary. In this paper, an accurate lowcost calibration method is presented. However, calibration does not take into account all influencing factors, especially when measuring fields close to the source (e.g., antenna). While measuring, the electromagnetic field will be disturbed by the measurement probes themsel...

The article describe systematically the electromagnetic (EM) side channels sources and electromagnetic field of the microprocessor and is focused on the best way how to measure the near electromagnetic field of microprocessor. It was suggested and realized several electromagnetic probes and it was performed the measurement regarded to the theoretical background on the testbed with cryptographic...

The dispersion of the measurement of electromagnetic disturbance above 1 GHz is mainly affected by site imperfections (expressed by SVSWR). To evaluate the uncertainty in electromagnetic disturbance measurements at 1 18 GHz, we measured SVSWR and the field strength at 9 measurement site. From our result, the measured field strength at each measurement site was observed in the range of 2σ that d...

Electromagnetic field probes inevitably change the original field distribution to some extent when they are positioned close to a device. That change affects measurement accuracy and the device operation. We have developed optical magnetic field probes, which comprise a loop antenna element and an electro-optic crystal, to perform magnetic nearfield measurement with high accuracy in the GHz fre...
