Simulation experiment of Inductive electric field measurement of Needle-ball electrode based on CST Microwave Studio

In recent years, UWB technology has gradually been widely used in many fields such as wireless communication, radar, positioning and electromagnetic pulse weapons. At the same time, it also plays an important role in ground radiation experiments such as aerospace. But in the experiment of electromagnetic radiation irradiation with UWB electromagnetic pulse, it is difficult to measure quantitatively. At the same time, it is disturbed by various factors and the measurement error is large. This paper simulates the UWB EMP signal by CST-MWS software and radiates the needle-ball electrodes. Through simulation calculation, it is found that there is a certain correlation between the induced voltage and electric field intensity between the electrodes of EMP and the intensity of EMP and the size of the electrodes.
