摘要： A metasurface element includes a support body and a metasurface formed on a surface of the support body. The metasurface includes a metal pattern that is disposed to emit an electron in response to incidence of an electromagnetic wave, and a metal layer that contains an alkali metal and is formed on the metal pattern. The metal layer extends beyond the metal pattern to reach a region on the surface of the support body, the region being not formed with the metal pattern.

摘要： An electron emitter includes an emitter layer formed of a dielectric material, an upper electrode, and a lower electrode. A drive voltage is applied between the upper electrode and the lower electrode, for emitting electrons. The upper electrode is formed of scale-like conductive particles on the upper surface of the emitter layer and has a plurality of opening portions. The surfaces of overhanging portions of the opening portions that face the emitter layer are apart from the emitter layer. The overhanging portions each have such a cross-sectional shape as to be acutely pointed toward the inner edge of the opening portion, or the tip end of the overhanging portion, so that lines of electric force concentrate at the inner edge.

摘要： An electron emitter includes an emitter section having a plate shape, a cathode electrode formed on a front surface of the emitter section, and an anode electrode formed on a back surface of the emitter section. A gap is formed between an outer peripheral portion of the cathode electrode and the front surface of the emitter section.

摘要： An electron emitting apparatus includes a lower electrode, an emitter section made of a dielectric material, a plurality of upper electrodes having micro through holes, and a collector electrode opposing the upper electrodes. In this electron-emitting apparatus, electrons are accumulated in the emitter section by controlling the potential difference (drive voltage) between the lower and upper electrodes with respect to the potential of the lower electrode to a negative predetermined voltage. At this time, the collector electrode of the electron-emitting apparatus is grounded. Thus, unnecessary electron-emitting is suppressed. Subsequently, the drive voltage is changed to a positive predetermined voltage. As a result, polarization reversal occurs in the emitter section, and accumulated electros are emitted through the micro through holes in the upper electrodes by Coulomb repulsion. At this time, a positive voltage Vc is applied to the collector electrode to give large energy to accelerate the electrons.
