high power microwave (HPM)
High Power Microwaves (HPM) are high power microwaves. They are narrowband microwaves in the frequency range between 500 MHz and 5 GHz with peak powers of several hundred megawatts ( MW). The power flux densities are above 500 W/sqm, the achievable field strengths are up to 500 V/m. High-power microwave technology is used in weapons technology for electromagnetic weapons.
