Security implications of high-power microwave technology

The development of high-power microwave (HPM) weaponry, and its proliferation into subversive organizations, offers the means to commit the "perfect crime." HPM attacks typically leave no residual evidence and their effects can range from nuisance to catastrophic. The paper highlights some of the unusual aspects of HPM technology and raises issues regarding security of airliners, commercial power systems and other targets. It also discusses strategies to begin mitigating the risks.
