Design of CHWHG Type Low Frequency Magnetic Fields Generator
Highly considering the invariability of magnetic field strength in the Magnetic Field Generators, which used to stimulate rat's nerve cell, surely improve the stimulation performance outcome. A new technique to get an invariable magnetic field strength within Magnetic Field Generator has been proposed, Furthermore it had implemented on microcontroller-based system providing an Alternating Magne...
متن کاملHigh Frequency Magnetic Fields in Treatment of Osgood-Schlatter Disease
We are studied efficacy of high frequency magnetic fields (HFMFs) in treatment of Osgood-Schlatter disease (OSD) including X-rays signs. THELF system apparatus has been used for treatments on 32 young sportsmen (9-15 years). 18 boys and 14 girls, with HFMFs (base frequency 27.125 MHz, with different impulse repetition frequency of 640 Hz and 320 Hz, and absorbed power 3-5 VA). Injured sportsmen...
متن کاملBroadband light generation by noncollinear parametric downconversion.
Broadband light generation is demonstrated by noncollinear spontaneous parametric downconversion with a cw pump laser. By use of a suitable noncollinear phase-matching geometry and a tightly focused pump beam, downconverted signals that feature a bell-shaped spectral distribution with a bandwidth approaching 200 nm are obtained. As an application of the generated broadband light, submicrometer ...
متن کاملCosmological Magnetic Fields by Parametric Resonance?
We investigate the possibility that electromagnetic fluctuations are amplified in expanding universe by parametric resonance, during the oscillatory regime of a scalar field to which they are coupled. We consider scalar electrodynamics and we find that electromagnetic fluctuations undergo exponential instabilities. This mechanism could have some relevance for the problem of large scale primordi...
متن کاملNoncollinear magnetic order in quasicrystals.
Based on Monte Carlo simulations, the stable magnetization configurations of an antiferromagnet on a quasiperiodic tiling are derived theoretically. The exchange coupling is assumed to decrease exponentially with the distance between magnetic moments. It is demonstrated that the superposition of geometric frustration with the quasiperiodic ordering leads to a three-dimensional noncollinear anti...
