Abstract
A tag detection system comprising a source for producing an interrogation signal having a first frequency; a harmonic radar tag comprising: an antenna structure; a tunneling junction electrically and integrally coupled to the antenna; and wherein the harmonic radar tag when stimulated by the interrogation signal having the first frequency, and the harmonic radar tag produces a response signal at a second frequency different from the first frequency.
