Analysis of Electromagnetic Pulse Coupling Inside Enclosure with Aperture Cable

In order to analyze the cable coupling characteristic of electromagnetic pulse inside enclosure with aperture, This paper uses the BLT equation to the calculate cable terminal response of the electromagnetic pulse enclosure with aperture. A set of cables as analysis object inside c enclosure with aperture, then using software analyzes the impact of different size of aperture, different type of cable on the cable coupling characteristic of electromagnetic pulse inside enclosure with aperture. The results show that when the size of the aperture is different, the strength of the electromagnetic pulse signal into t enclosure with aperture is different, and then on the cable induced voltage will be different. When the type of cable is different, electromagnetic pulse into enclosure with aperture produces induced voltage on the cable is also different. This paper chooses single line and shield coaxial as analysis object, the simulation results show that the shield coaxial line has more than 20 dB than single wire about shielding effect.
