Abstract: The electromagnetic fields radiated by electrostatic discharge is analyzed using the bipolar model. The transient electric and magnetic fields generated by electrostatic discharge from the charged human body during the operation of computers are measured by a very high sampling rate oscilloscope and custom-made wide band electric field and magnetic field antennas. The spectrum of the fields is analyzed by FFT. The influence of the fields on high frequency signals is studied. The results show that the electric fields can be several hundred V/m and the magnetic fields can be several A/m even if the discharge voltage is very low(2kV).The spectrum of the fields is very wide ranging from several MHz to several GHz.The effects of the fields on high frequency circuits show that some influences such as “latent effects” on integrated circuits or devices, electromagnetic interference and even damage to the circuits can be caused by the electromagnetic fields generated by electrostatic discharge from the charged human body.
