Wireless RF Multifrequency Resonator for the Non-Invasive Monitoring of Tumors in Breast Tissues

Abstract

A novel inductive multifrequency passive resonator is used to sense dielectric objects in the context of breast tumor characterization. It aims to monitor breast tumors evolution wirelessly in the radiofrequency range. This paper shows an electrical equivalent modelling of the proposed sensor and an example of an application consisting of the detection of a 1.5 cm diameter sphere filled with a conductive solution.
