Abstract:
1. A spark gap switch for high power ultra-wideband electromagnetic wave radiation, comprising: a casing having a cylindrical shape, with openings formed in respective opposite ends of the casing; a plurality of electrodes installed in the casing at positions spaced apart from each other by a predetermined distance in such a way that the electrodes face each other and are disposed inside the openings, wherein surfaces of the electrodes that face each other comprise planar or curved surfaces; a plurality of brackets installed in the respective openings of the casing, the brackets fastening rear ends of the corresponding electrodes to the casing; and an electrode protrusion provided on a central portion of at least either of the electrodes, the electrode protrusion inducing stabilized discharge, wherein each of the electrodes has a “U” shape, wherein an electrode assisting member is provided on a central portion of at least either of the electrodes and a peripheral portion of the central portion and is made of different material from the electrodes, and wherein the electrode protrusion is disposed on a central portion of the electrode assisting member and is made of material equal to the material of the electrode assisting member.
