In this paper, current-voltage characteristic of a resonant tunneling diode under electromagnetic radiation has been calculated and compared with the results when there is no electromagnetic radiation. For calculating current -voltage characteristic, it is required to calculate the transmission coefficient of electrons from the well and barrier structures of this device. For calculating the tr...

Introduction: In recent years, use of compact fluorescent lamps has increased in order to optimize energy consumption. The aim of this study was to evaluate the radiations of electromagnetic spectrum from usual compact fluorescent lamps. Methods: In this study, 48 compact fluorescent lamps from different brands and cover (warm – cool) were selected. For studied lamps, operational facto...
This paper presents a low-profile, planar electromagnetic vibration energy harvester integrated with a Halbach array. Halbach array is a special arrangement of permanent magnets that doubles the magnetic field on one side of the array while cancelling the field to near zero on the other side. Using this arrangement can improve electromagnetic coupling in a limited space. The energy harvester ha...
It is considered constraints imposed by the quantum mechanics on the measurement of the density of the electromagnetic energy. First, the energy of the electromagnetic wave and the volume (time) are bound with the Heisenberg uncertainty principle. It reduces from double to ordinary the relativistic effect for the density of the electromagnetic energy. Second, the frequency of photons and the nu...
Developing technology and industry and increasing application of electromagnetic fields in medicine, threaten the environment and human health. Biological effects of these fields depend on the field magnitude and physical characteristics of exposed tissue. In order to research the effects of electromagnetic fields on kidney tissue on electromagnetic field generator was made with intensities of ...
