Influence of electrode size for electromagnetic radiation due to micro gap discharge in spherical electrode

Relation between discharge voltage and amplitude of electromagnetic radiation was examined in experimental study. The amplitude of electromagnetic radiation was proportion to the voltage gradient at the gap in the resonance experimental system using the discharge electrode with dipole configuration. In this time, we present an improved experimental system to measure the radiated electromagnetic waves in the frequency range from 1 GHz to 3 GHz using a pear of spherical electrode and a horn antenna. As a result, the amplitude of received voltage is proportion to the discharge voltage (charged voltage of the electrode) from 300V to 620V, and the received voltage is proportion to the diameter of spherical electrodes.
