Three different methods in combination with integration of differences in signals were applied for EEG analysis to distinguish changes in EEG caused by microwave: S-parameter, power spectral density and length distribution of low variability periods. The experiments on the effect of modulated low-level microwaves on human EEG were carried out on four different groups of healthy volunteers exposed to 450 MHz microwave radiation modulated with 7 Hz, 14 Hz, 21 Hz, 40 Hz, 70 Hz, 217 or 1000 Hz frequencies. The field power density at the scalp was 0.16 mW/cm2. The EEG analysis performed for individuals with three different methods showed that statistically significant changes occur in the EEG rhythms energy and dynamics between 12% and 30% of subjects.
结合信号差异积分采用三种不同方法进行脑电图（EEG）分析，以区分微波引起的EEG变化：S参数、功率谱密度和低变异性周期的长度分布。对四组不同的健康志愿者进行了关于调制低强度微波对人类EEG影响的实验，这些志愿者暴露于频率为7Hz、14Hz、21Hz、40Hz、70Hz、217Hz或1000Hz调制的450MHz微波辐射下。头皮处的场功率密度为0.16mW/cm²。采用三种不同方法对个体进行的EEG分析表明，12%至30%的受试者的EEG节律能量和动态出现了具有统计学意义的变化。
