UNCLASSIFIED /7POR OFFICAL USE ONE Pulsed High-Power Microwave Source Technology Summary This paper provides an overview of the major types of high-power microwave (HPM) sources and the critical technologies required to build them. Pulsed HPM technology has been of scientific and military interest for several decades. Originally, the interest focused on the area of high-altitude electromagnetic pulse (HEMP) concerns. HEMP is produced when a nuclear weapon is detonated high above the earth’s surface, creating gamma radiation that interacts with the atmosphere to create an intense electromagneti…

UNCLASSIFIED (fPO@R“*OPfEECERE USE ONE? One major use of HPM by the military is for electronic attack, or what is referred to by the media as an “ebomb.” HPM sources developed for this purpose provide peak powers in excess of 10 gigawatts. The goal of such a weapon is to disable communications and computer systems prior to any troop movements and render the enemy unable to stage a response. The technology used to drive such sources has its roots in pulsed power, and for narrowband sources requires the use of tools that have been developed in the plasma physics community. Reliance on microproce…

UNCLASSIFIED sth ORG GELGEAL LSE Me, a PRR is applied such that there is insufficient time for thermal diffusion between pulses (about 1 millisecond), then there will be an overall constant rise in temperature. For this reason, the PRR capability is of extreme importance for any HPM source. As a matter of course, assets to be tested include those of friend and foe alike, the goal being to find vulnerabilities in both and correcting those found in our own assets. Several techniques are employed to mitigate vulnerabilities found in assets, including filtering of conductor lines, using metallic e…
