Experimental Design for Verifying the Time-Frequency Domain Performance of Specular Single Cone Electric Field Standard Devices

This study proposes a method to verify the time domain and frequency domain performance of specular single cone electric field standard devices, drawing on an analysis of relevant international and domestic standards and research. In the time domain, pulse waveform parameters (amplitude, rise time, pulse width) of the transient electromagnetic pulse electric fields generated by both the specular single cone electric field standard device and the TEM chamber are compared. In the frequency domain, the comparison is made between the continuous-wave electric field strengths generated by the specular single cone device and the μTEM chamber. The E_n value is employed to assess the comparison results in both time and frequency domain performance verifications. This research, focusing on the development of a time-frequency domain performance verification method for specular single cone electric field standard devices, addresses the challenges in verifying both time and frequency domain performances of these devices. It is crucial for ensuring the accuracy of pulse electric field measurements in China and for harmonizing the transient pulse electric field parameters.
