In this study, the efficiencies of seed priming with electromagnetic field (0, 2, 4, and 6 mT; 30 minutes daily for 3 days) were investigated in Salvia nemorosa. The exposure to electromagnetic filed led to significant increases in biomass accumulation (mean=53.6 %). Electromagnetic filed treatments significantly increased K, Ca, Mg, and Fe contents in leaves by mean 39.5 %. The electromagnetic...

where E [V/m] is the amplitude of effective value of the electric field, σ [S/m] and ρ [kg/m] are the electric conductivity and the density of human tissue, respectively. In general, an approximation of a plane wave for the electromagnetic field has been applied to E in eq. (1) in order to represent the SAR characteristics in the internal parts of the head [1], [4]. For example, attenuation cha...

We design a high dynamic range electric field sensor based on domain inverted electro-optic (E-O) polymer Y-fed directional coupler for electromagnetic wave detection. This electrode-less, all optical, wideband electrical field sensor is fabricated using standard processing for E-O polymer photonic devices. Experimental results demonstrate effective detection of electric field from 16.7V/m to 7...

Great social concern has risen about the potential health hazard of living near a cellular telephony base-station antenna, and certain technical questions have been posed on the appropriate way to measure exposure in its vicinity. In this paper, standard spherical near–near field transformation is proposed to obtain the electromagnetic field close to the antenna in free space conditions. The fi...

Introduction: Results of several studies on different effects of electromagnetic waves reveal that change of field intensity, even milli tesla has various biological effects, therefore investigation on electromagnetic effects can be done in very wide range. In this research, amount of these effects on biomass, thymus, testis and therapeutic role of vitamin C in...

The problem of reduction of the wave packet of a relativistic charged particle by emission of a photon is studied with help of the path integral approach. A general expression for arbitrary order correlation function of the electromagnetic field is obtained. As a specific example an ultrarelativistic electron circulating in a storage ring is considered. It is shown that the longitudinal width o...

BACKGROUND The activities of rescue and uniformed services require the use of wireless communication devices, such as portable radiophones. Assessment of workers' exposure to electromagnetic fields emitted by radiophones is important in view of occupational safety and health (OSH), legislation requirements and reports on possible adverse health effects in users of devices emitting radiofrequenc...

− The theory of electromagnetic shielding is based on the waves equations describing the behavior of electromagnetic field in substance and also boundary phenomena by means of Fresnel’s reflection and transmission coefficients. The interaction between electromagnetic radiation and infinite plane shield having finite thickness d, placed in free space in plane waves region depends of material/shi...
