How it Works

ResCav Prototype

Inside Resonant Cavity

ResCav obtains unique signature of IC when placed inside resonant cavity

Signature is unique to structural, material and circuit properties of IC

Machine Learning algorithms allows ResCav to precisely detect counterfeit ICs

Resonant Cavity: Hollow closed metal box with electromagnetic (EM) waves reflecting and forth between the cavity walls

Resonant frequencies occur at integer multiples of the wavelengths of the wave

A rectangular resonant cavity, and the electric field variations for the TE101 and TE102 resonant modes (m, n, p)

Resonant frequency shift determined by:
