Abstract

In this paper, we evaluate the susceptibility of notebook computers to high power microwave (HPM) pulses. We have developed a HPM test instrument with stripline structure. The structures of the test instrument are investigated through finite-difference time domain (FDTD) analysis to get homogeneous electromagnetic fields inside the instrument. The developed instrument can apply a 2.7 kV/m electric field below 3 GHz with using a 100 W power amplifier. The stripline instrument is an open structure, which can easily apply electric fields to a specific part of notebook computers. The HPM pulses were applied to the main body of notebook computers. We obtained the frequencies of the HPM pulses at which the notebook computer operation has failed. Radiated susceptibility tests were also carried out on notebook computers with an antenna. The computer failure frequencies of the test instrument agree with the failure frequencies from observed during the radiated susceptibility test. Our test instrument is useful for preliminary test of notebook computers and for investigating the effective HPM pulse condition.

笔记本电脑对HPM的易感性

在本文中，我们评估了笔记本电脑对高功率微波脉冲的敏感性。我们研制了一种带状线结构的HPM测试仪。通过时域有限差分分析(FDTD)对测试仪器的结构进行了研究，得到了仪器内部的均匀电磁场。该仪器采用100w功率放大器，可在3ghz以下施加2.7 kV/m的电场。带状线仪器是一种开放式结构，可以很容易地将电场施加到笔记本电脑的特定部位。将HPM脉冲应用于笔记本电脑的主体上。我们得到了笔记本电脑操作失败时HPM脉冲的频率。还对带有天线的笔记本电脑进行了辐射敏感性试验。试验仪器的计算机故障频率与辐射敏感性试验中观察到的故障频率一致。本仪器可用于笔记本电脑的初步测试和HPM有效脉冲状态的研究。
