Measurement of High-Power Microwave Impulse Response Characteristics of Reflector Materials
International Journal of Antennas and PropagationHigh-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.

An EIRP Measurement Method of High-Power Microwave Systems Based on Near-Field Testing
International Journal of Antennas and PropagationThe 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.
