METHOD AND DEVICE FOR GENERATING HIGH-FREQUENCY ELECTROMAGNETIC WAVE SIGNAL

摘要

PROBLEM TO BE SOLVED: To provide a method and a device for generating an electromagnetic wave signal in a GHz band due to gaseous discharge easily and with excellent reproducibility, to easily investigate an influence of the gaseous discharge on insulation assessment by a UHF method, or an influence on EMC, without providing large-scale experimental equipment. SOLUTION: A gas insulation section and a solid insulator are provided between an upper electrode and a lower electrode being a pair and facing each other, and a floating metal section is provided between the gas insulation section and the solid insulator. By applying a power source voltage between this pair of electrodes, high-frequency electromagnetic wave signals from the VHF band up to the SHF band are generated while centering mainly on the UHF band.
