Title

(EN) SYSTEMS AND METHODS FOR COMPUTERIZED TOMOGRAPHY WITH LOW FREQUENCY ELECTROMAGNETIC RADIATION

(FR) SYSTÈMES ET PROCÉDÉS DE TOMOGRAPHIE INFORMATISÉE À RAYONNEMENT ÉLECTROMAGNÉTIQUE BASSE FRÉQUENCE

Abstract

(EN) Systems and methods for performing computerized tomography using low frequency electromagnetic radiation are disclosed. In one embodiment, a system for performing computerized tomography of an object under test using low frequency electromagnetic radiation comprises: a transmitter antenna configured to emit low frequency electromagnetic radiation towards the object under test; and a receiver comprising a metasurface having a plurality of receiver antennas configured to receive the low frequency electromagnetic radiation emitted from the transmitter antenna after passing through the object under test.

(FR) L'invention concerne des systèmes et des procédés destinés à effectuer une tomographie informatisée à l'aide d'un rayonnement électromagnétique basse fréquence. Dans un mode de réalisation, un système destiné à effectuer une tomographie informatisée d'un objet en cours de test à l'aide d'un rayonnement électromagnétique basse fréquence comprend : une antenne émettrice configurée pour émettre un rayonnement électromagnétique basse fréquence vers l'objet testé ; et un récepteur comprenant une métasurface ayant une pluralité d'antennes réceptrices configurées pour recevoir le rayonnement électromagnétique basse fréquence émis par l'antenne émettrice après avoir traversé l'objet testé.
