Abstract
A material detector includes a pulse generator to generate pulses to excite molecules in the material and a detector to detect a signal generated from excited molecules in the terahertz region. Spectral features in the material are analyzed to identify the material. Detection can be performed using a nanoantenna array structure having antennas tuned to detect the expected spectral emission. The nanoantenna array can include antennas having MIM or MIIM diodes. Signal processing and statistical analysis is use to reduce false positives and false negative in identifying the material.
