Numerical Simulation of Metal Platform Influence on Spark Discharge Electromagnetic Radiation Field
A spark discharge experiment was designed to test the breakdown voltage and calculate corresponding discharge energy, which also provided basis on researching electromagnetic radiation features of spark discharge and metal platform influence on it. According to the simulation software - FEKO, physical models with and without metal platform were founded and different radiation patterns were simulated under a range of frequencies. The radiation pattern of model without metal platform is similar with dipole model, comparing with that, the pattern of model with metal platform is mainly on the upper side of metal platform when frequency is getting higher. The band around 700 MHz was considered to be hazardous, and easy to induce radio frequency current and secondary spark discharge in other radio receivers, while metal platform can enhance this effect.
