  1. 1. Effects of Lightning Electromagnetic Pulse and High Power Microwaves on Military Electric Systems

    Författare :Stefan Silfverskiöld; Michel Ianoz; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Engineering physics; LEMP; HPM; electronic warfare; anechoic chamber; reverberation chamber; Teknisk fysik; Engineering physics; Teknisk fysik; Electricity; Esp The Study Of Transients and Discharges; elektricitetslära; ssk studiet av transienter och urladdning;

    Sammanfattning : The awareness of the threat posed by Lightning Electromagnetic Pulse (LEMP) and High Power Microwaves (HPM) against the operational reliability of electric systems is rapidly growing. This has led to an increasing need for reliable tools, experimental as well as theoretical, for design, analysis and verification of system immunity against electromagnetic threats. LÄS MER

    Sammanfattning : Each reduction of the technology node has, along with improvements in IC fabricationtechnology, been the main driver in delivering the demand for function rich, integratedmobile electronics that are so prevalent. As devices keep growing smaller and geometriesapproach the order of a few atomic layers, it is increasingly difficult to achievecost-effective mass production for reasons related to performance and fabrication capability.
