Abstract

La présente invention concerne un manteau d'invisibilité de protection contre les impulsions électromagnétiques ayant une structure sphérique. Le manteau d'invisibilité est constitué de plusieurs couches de protection empilées. Une plaque de terre annulaire est disposée au niveau d'une portion inférieure du manteau d'invisibilité. De multiples tubes métallisés sont disposés à l'intérieur du manteau d'invisibilité. Les tubes métallisés traversent perpendiculairement les couches de protection et sont reliés à la plaque de terre annulaire. Chacune des couches de protection est pourvue de multiples pistes circulaires agencées d'un côté intérieur vers un côté extérieur. Chacune des pistes circulaires est pourvue de multiples unités de protection disposées de manière séquentielle. Les tubes métallisés traversent perpendiculairement les couches de protection et sont reliés à la plaque de terre annulaire. Les tubes métallisés sont pourvus de trous métallisés. Les unités de protection comprennent quatre bobines d'induction reliées en parallèle et un condensateur et le condensateur est relié aux trous métallisés. La présente invention peut être mise en œuvre afin de réfléchir, d'absorber ou d'atténuer complètement des impulsions électromagnétiques, de sorte qu'un objet protégé ne soit pas influencé par les impulsions électromagnétiques.
