We seek to build imaging arrays for screening personnel through portals using new microwave circuits that produce coherent signals of electronic terahertz THz generation and detection integrated circuits. Since we have demonstrated that these circuits can distinguish reflection signatures of a variety of threats from those of clothing and skin, they can be used for screening human subjects working in conjunction with established metal screening portals, which will provide a completely new measure of threat imaging and hence security. We developed a broadband electronic THz system capable of reflection and transmission spectroscopy of materials. We also developed broadband antennas with nearly 20 dB of gain that can be integrated with such THz systems.
