Ultra-low frequency wireless transmitter design using resonant oscillating permanent magnets
Electromagnetic signals in the ultra-low frequency (ULF) range of 3-3000 Hz has low signal attenuation and high penetration depth, making them ideal for underwater and underground wireless communication systems. However, the large wavelength of ULF signals (10^2-10^5 km) necessitates conventional …

In-vitro experiments on neuronal cells and computer modeling over realistic head models in TMS
<p>Transcranial magnetic stimulation is a neuromodulation technique that can be used as a non-invasive method for treating various neurological disorders. The major principle of TMS is the Faraday’s law stating that time varying magnetic field induces electric field in nearby conductors. More …

Development of Novel Eddy Current Dampers for the Suppression of Structural Vibrations
… damping to the membrane structure is to use magnetic damping. Magnetic dampers function through the eddy currents that are generated in a conductive material that experiences a time varying magnetic field. However, following the generation of these currents, the internal resistance of the …
