IEC, ETSI and other international standard organizations have drawn general standards for specific absorption rate (SAR) of EM radiation from various handle wireless communication equipment in the near field, and keeps on consummating related product standards. Comparing with the expensive and long time testing, the simulation technique has outstanding advantages, and it is applicable in terminal...
The progress and characteristics of gas discharge is studied in this paper by numerical simulation. A program based on the FE-FCT method in its full two-dimension form is developed and employed for the solution of transport equations of charged species under the effect of space-charge electric field. Results of two-dimensional simulation of cylindrically symmetric streamers in air between Point-plane...
ATEM cell is widely used in electromagnetic compatibility (EMC) test. When loaded with equipment under test (EUT), the electric field in ATEM cell will be distorted , and the characteristic impedance changed. In this paper, the field distribution and characteristic impedance in ATEM cell loaded with rectangular metallic EUT is analyzed by a simple method---point matching method. The section of an...
In this paper, electric field near ground during thunderstorm process is discussed with field data measured by thunderstorm electric field mill and numerical simulation. The measured field data shows that the atmospheric field became strong as measure height increased. The cause is given out by the numerical simulation. And the result of numerical simulation shows accordance with measured data. The...
