چکیده

A fundamental model consisting of charged particles moving in free space exposed to alternating and direct current (ACDC) electromagnetic fields is analyzed. Effects of charged particles initial position and initial velocity to cyclotron resonance frequency are observed. Strong effects are observed revealing that effects of electric and magnetic fields on a charged particle in free space varies with the initial conditions. This indicates the frequency where maximum displacement occur can be changed. At this frequency the amplitude of oscillation of the particle displacement becomes unbounded. Keywords—Cyclotron resonance, electromagnetic fields, particle displacement

The effects of weak extremely low frequency magnetic fields on calcium/calmodulin interactions.

Mechanisms by which weak electromagnetic fields may affect biological systems are of current interest because of their potential health effects. Lednev has proposed an ion parametric resonance hypothesis (Lednev, 1991, Bioelectromagnetics, 12:71-75), which predicts that when the ac, frequency of a combined dc-ac magnetic field equals the cyclotron frequency of calcium, the affinity of calcium f...

Pulsed electromagnetic field at frequency and intensity resembling potassium ion cyclotron resonance selectively impairs breast cancer cell through apoptosis

Introduction: Breast cancer (BC) is the most common women cancer worldwide. Radiotherapy and chemotherapy are the two common treatment options but these techniques suffer low selectivity and adverse effects on surrounding normal tissues. Non- ionizing pulsed electromagnetic fields (PEMFs) in ultra-narrow band frequency and intensity have shown anticancer effects. Changing potas...

AC Electrophoresis; Deposition of Ceramic Nanaoparticles on In-plane Electrodes at Low Frequencies (RESEARCH NOTE)

Deposition of ceramic nanoparticles (dispersed in a non-aqueous suspension) on in-plane electrodes and under the influence of AC electric fields in the frequency range of 0.01 Hz - 10 kHz is investigated. Analysis of the particle response to the applied field is a difficult task due to the mutual effect of electric- and hydrodynamic force which are present in the system. In this work, however, ...

Thick Film Deposition of Carbon Nanotubes by Alternating Electrophoresis

Electrophoretic deposition of carbon nanotubes (CNTs) using alternating current electric fields (0.01-1000 Hz) is reported. Pure acetone was used as suspending medium. Two parallel gold electrodes were used as depositing substrate. The effect of depositing parameters such as frequency and three waveforms (sinusoidal, rectangular and triangular) on deposit yield was investigated. According to ou...
