Submillimeter-wave Vector Measurements for Explosive Materials SBIR TOPIC NUMBER: H-SB09.1-002 TITLE: Submillimeter-wave Vector Measurements for Explosive Materials TECHNOLOGY AREAS: Detection of Explosives OBJECTIVE: Provide full S-parameter characterization systems for frequencies from W-Band (75-110 GHz) to 1 THz suitable for use in the characterization of explosive materials. DESCRIPTION: The Explosives Division of DHS Science and Technology Directorate is investigating imaging systems for the detection of concealed explosive materials using submillimeter-wave electromagnetic radiation, specifically in the frequency range from about 100 GHz up to 1 THz. Commercial Vector Network Analyzer (VNA) systems now operate well up to about the WR-10 waveguide band (75-110 GHz), and with decreasing performance up to about WR-2.2 (335-530 GHz). These systems are useful for the characterization of the electromagnetic properties of explosive materials in the laboratory. The goal of this topic is to develop, demonstrate and deliver a modular frequency extender system that achieves 100dB of dynamic range across full waveguide bands throughout this entire frequency range. The system must be suitable for simultaneous measurement of all four S-parameters of explosive materials in a laboratory environment with high dynamic range and extendable up to 1 THz. Specific Requirements of the System Include: A modular, reconfigurable system that covers the full frequency range (~100 GHz - 1THz), with each configuration covering an entire waveguide band. Simultaneous measurement of all four S-parameters. Dynamic range of 100dB or greater. The extender system must have interface capability with modern VNA systems; such as Agilent, Rohde & Schwarz, and others). System must be suitable for use in a wide range of laboratory applications, ultimately extendable to 1 THz and suitable for commercialization. PHASE I: The Phase I Program is focused on demonstrating the transmitter and receiver technology across full waveguide bands with suitable performance to achieve ~100dB of dynamic range. As a minimum, Phase I must include a demonstration of S11 and S12 measurements across a full waveguide band above 400GHz with ~100dB dynamic range. All system components including the required the transmitter, receiver, reference receiver and couplers must be demonstrated with an operational interface to a modern VNA system. However, high precision calibration is not required until Phase II. This extender system must be delivered for evaluation. PHASE II: A working prototype extender must be delivered at the completion of the Phase II that covers the entire frequency range (~100 - 1,000GHz) with dynamic range of 100dB or better and full four port measurement. Calibration techniques must be established. This extender system must be delivered in Phase II for evaluation purposes. PHASE III - COMMERCIAL APPLICATIONS: While this technology is specifically being assessed for the laboratory evaluation of explosive materials, it should be suitable for a wide range of laboratory measurements; including chemical analysis, compact range radars, terahertz component evaluation and development, measurements of biomaterials, etc.
