Experimental study on microwave radiation effects on personal computer

The microwave radiation effects on a personal computer are investigated experimentally in the frequency range from 1.2 to 2.0 GHz. The microwave power threshold for the computer to be crashed is studied under various microwave carrier frequencies, modulation types and modulation degrees. The microwave power thresholds are obtained under 4 computer operating states, the full CPU load, the disk operating, the memory reading and writing and the system idle. The microwave radiation effect on the computer during system booting is also studied. The experimental results show that when the microwave carrier frequency is 1.47 GHz, the computer is interfered most easily. At low modulation frequency, the instantaneous microwave power is the key effect factor of the microwave radiation on the personal
