Abstract

LES ARTICLES A IDENTIFIER CONTIENNENT UNE PETITE PROPORTION (ENVIRON 0,5 A 5 EN POIDS) DE TRES FINES FIBRES CONDUCTRICES QUI ABSORBENT ET REFLECHISSENT DES PROPORTIONS NOTABLES D'UN RAYONNEMENT HYPERFREQUENCE INCIDENT. ON FAIT PASSER LA PARTIE DE L'ARTICLE CONTENANT CES FIBRES A TRAVERS UN FAISCEAU HYPERFREQUENCE NON GUIDE, ENTRE UN EMETTEUR 4 ET UN RECEPTEURS 5. LA QUANTITE D'ENERGIE REFLECHIE EST CAPTEE DANS UN CAPTEUR 8 TANDIS QUE LA PARTIE TRANSMISE A TRAVERS L'ARTICLE EST MESUREE PAR UN CAPTEUR 7 QUI MESURE AINSI LA QUANTITE D'ENERGIE ARRETEE. UN COMPARATEUR RECOIT LES SIGNAUX DE 8 ET DE 7 ET PRODUIT UN SIGNAL DE SORTIE REPRESENTATIF DE LA PRESENCE D'UN EXCEDENT NOTABLE DE L'ENERGIE ARRETEE PAR RAPPORT A L'ENERGIE REFLECHIE.
