High power microwave weapon system
View Patent ↗This invention allows combining broadband GW(10 +9 Watt), peak power to achieve MV/m(10 +6 Volt/meter), and GV/m(10 +9 Volt/meter), radiated E-fields, in the range of air or vacuum breakdown in the entire electromagnetic spectrum, including optical frequencies and beyond. Use of many antennas and independently triggered generators allows achieving GV/m field, while by preventing the E-field induced breakdown it provides control of peak power and energy content at targets. The achieved broadband MV/m E-field levels and energy density significantly exceed levels required for destruction of distant electronic targets; therefore this invention radically improves the effectiveness of the electromagnetic weapons. Furthermore, collimating multiplicity of MV/m beams allows reaching GV/m E-field that exceeds by orders of magnitude the air or vacuum breakdown needed for broadband plasma excitation at resonance plasma frequencies in the 300 GHz range.
