Electronic pulse generation device

An electronic pulse generation device comprising:

• an emitter element made of a dielectric material;
• first and second electrodes formed in contact with said emitter element;
• means for applying an alternating pulse between said first electrode and said second electrode to reverse or change polarization of said emitter element;
• wherein said means for applying alternating pulse applies a first voltage between said first electrode and said second electrode for causing said first electrode to have a potential higher than a potential of said second electrode in a first period to perform said polarization of said emitter element in one direction,
• wherein said means for applying alternating pulse applies a second voltage between said first electrode and said second electrode for causing said first electrode to have a potential lower than a potential of said second electrode in a second period to perform said polarization reversal or polarization change of said emitter element for emitting electrons, and
• wherein electrons are emitted intermittently from said emitter element.

An electronic pulse generation device comprising:

• an emitter element made of a dielectric material;
• first and second electrodes disposed in contact with a principal surface of said emitter element, with a slit defined between said first electrode and said second electrode, said emitter element being partly exposed through said slit;
• and
• means for applying an alternating pulse between said first electrode and said second electrode to reverse or change polarization of said emitter element,
• wherein electrons are emitted intermittently from said emitter element.

An electronic pulse generation device comprising:

• an emitter element made of a dielectric material;
• a first electrode formed on a first surface of said emitter element;
• a second electrode formed on a second surface of said emitter element;
• and
• means for applying an alternating pulse between said first electrode and said second electrode to reverse or change polarization of said emitter element,
• wherein polarization reversal or polarization change occurs in an electric field E applied to said emitter element represented by E=Vak/h, where h is a thickness of said emitter element between said first electrode and said second electrode, and Vak is a voltage between said first electrode and said second electrode, and
• wherein electrons are emitted intermittently from said emitter element.

An electronic pulse generation device comprising:

• an emitter element made of a dielectric material;
• first and second electrodes formed in contact with said emitter element;
• and
• means for applying an alternating pulse between said first electrode and said second electrode to reverse or change polarization of at least a portion of said emitter element,
• wherein said first electrode, said emitter element and a vacuum atmosphere define a triple point,
• wherein the polarization reversal or polarization change causes positive poles of dipole moments in the vicinity of said first electrode to be oriented toward said first electrode, thereby inducing emission of primary electrons from a portion of said first electrode in the vicinity of said triple point, and
• wherein said emitted primary electrons impinge upon said emitter element to induce emission of secondary electrons from said emitter element.
