A three dimensional Brownian Dynamics(BD) in combination with electrostatic calculations is employed to specifically study the effects of radiation of high frequency electromagnetic fields on the conduction and concentration profile of calcium ions in side the voltage gated calcium channels.The electrostatic calculations are performed using COMSOL Multiphysics by considering dielectric interfaces effectively. The simulations are performed for different frequencies and intensities.The simulation results show the variations of conductance,average number of ions and the concentration profiles of ions inside the channels in response to high frequency radiation.The ionic current inside the channel increases in response to high frequency electromagnetic field radiation,and the concentration profiles show that the residency of ions in the channel decreases accordingly.
