A traditional idea with respect to the interaction of electromagnetic fields and biologic systems is that specific effects can occur only when the incident energy is greater than the energy associated with a temperature that is characteristic of the biologic system (kT). The functioning of the visual system and the effect of ionizing radiation are examples of these interactions. For energies le...

Heating of the ionosphere by high-frequency (HF), ordinary (O) mode electromagnetic waves can excite magnetic field aligned density striations (FAS), associated with upper and lower hybrid turbulence and electron heating. We have used Vlasov simulations in one spatial and two velocity dimensions to study the induced turbulence in the presence of striations when the O-mode pump is mode converted...

a large body of evidence now indicates that the amount of mercury released from dental amalgam fillings can be significantly accelerated by exposure to radiofrequency electromagnetic fields (rf-emfs) such as common mobile phones and magnetic resonance imaging (mri). studies performed on the increased microleakage of dental amalgam restorations after exposure to rf-emfs have further supported th...

The paper examines the modern electromagnetic software available in the market (Multiphysics by ANSYS, QuickWave-3D by QWED, EMC2000-VF by Matra Systemes & Information, Microwave Studio by CST, and some others) with respect to their applicability to the typical problems of microwave power engineering. The solutions to the especially designed benchmark problem (2.45 GHz microwave oven) obtained ...

Abstract To solve the problems of electromagnetic heating cigarette devices in speed and temperature control accuracy, optimization system was carried out based on current device. And special for device designed, which powered by a lithium battery designed with half-bridge push-pull double resonant capacitor. According to test, prototype can preheat at 350 °C 7 seconds fastest, an average rate ...

Hot air and hot water heating methods have been extensively studied as thermal treatments to control insect pests in fruits to replace chemical fumigation. An inherent difficulty in using these methods is that slow heating rates may result in long treatment times and possible damage to fruit quality. Many factors influence heating time. A systematic analysis of those influences is desirable to ...

Thermally modulated photoacoustic imaging (TMPI) is reported here for contrast enhancement when using nanoparticles as contrast agents. Exploiting the excellent sensitivity of the photoacoustic (PA) process on temperature and the highly selective heating capability of nanoparticles under electromagnetic field, the PA signals stemming from the nanoparticles labeled region can be efficiently modu...
