Abstract

Abstract

A simple measurement system for the shielding effectiveness is developed, and a method for measuring pulse electric field shielding effectiveness of shielding body is presented. The system is made up of pulse electric field radiation device and its receiver. The rising time of the pulse electric field radiated by the device is less than 3.3 ns, the falling time more than 5 μs, and the peak value more than 7.5 kV/m at 60 cm in front of the antenna. Optic fiber device is used in the system for electronic field measurement, and the powerful EMI is restrained. The measurement program is written in Matlab language for automation and signal processing. The system has 97 dB dynamic range and is portable. Experimental results show that the attenuation of the maximum electric field value can refle
