Abstract :
New ways to detect non metallic weapons such as explosives and ceramic handguns in order to secure public places have to be developed. To do so, we use millimeter-waves (frequency comprised between 18 and 40 GHz) at which human body is highly reflective and clothes almost invisible. We developed a multipoint sensor based on a chaotic high-Q cavity filled with millimeter-waves. It relies on the contrast that exists between the refractivity of human body and the refractivity of dielectrics
