An EIRP Measurement Method of High-Power Microwave Systems Based on Near-Field Testing

International Journal of Antennas and Propagation
The equivalent isotropic radiated power (EIRP) of high-power microwave (HPM) systems is a core-evaluating indicator. In practical testing, locating a suitable test site for the far-field method becomes challenging due to the requisite antenna separation.

Measurement of High-Power Microwave Impulse Response Characteristics of Reflector Materials

International Journal of Antennas and Propagation
High-power microwave (HPM) antenna, one of the key subsystems in the HPM system, is used for HPM radiation. Its performance is partly determined by the impulse responses of reflector materials under HPM.

A compact high power microwave (HPM) source [PDF]

IET European Conference on European Pulsed Power 2009. Incorporating the CERN Klystron Modulator Workshop, 2009
A compact high power microwave (HPM) source is reported. It generates short pulses by direct excitation of an antenna with a 300 kV Marx generator. Oil insulation is used to protect capacitor banks from breakdown, while discharge gaps are designed to work in air. The Marx generator risetime is less than 50 ns.
