Modular Frequency Extenders for Vector Network Analyzers

Virginia Diodes Incorporated
979 Second Street SE
Suite 309
Charlottesville, VA 22902-6172


Modular system will be developed to extend the frequency range of Vector Network Analyzers to at least 1 THz. These extenders will offer excellent dynamic range and stability, as well as the capability for fully calibrated measurements. The extenders will rely on innovative full waveguide band frequency multipliers and mixers that utilize planar, integrated Schottky diode circuits. The modular extender systems will allow rapid reconfiguration of the components for operation in multiple waveguide bands, while maintaining low cost. During Phase 1 VDI demonstrated the modular extender concepts and delivered a WR2.2 frequency extender with exceptional dynamic range and excellent stability. Phase 2 will emphasize the development of modular extenders for the complete 100GHz to 1,000GHz frequency band. This includes development of the individual components that most affect system performance, as well as the development of the extender systems to yield reliable and cost effective products. The deliverable system, covering 100GHz to 1,000GHz, will serve as a prototype for the sales of VNA extenders for the wider commercial market; which includes national, industrial and university research laboratories that are developing new technologies and applications for the terahertz frequency band.

Hard Drive Unlocking

Evidence Preserving Hard Disk Unlocking System

Luna Innovations Incorporated
1 Riverside Circle
Suite 400
Roanoke, VA 24016-4962


Luna Innovations will design and develop a hard disk unlocking system that is easily usable by forensic technicians while preserving evidentiary integrity. Our solution will be robust even against anticipated future drive features and drives modified by criminals to have certain anti-tamper properties. This is important as it is nearly certain that manufacturers or criminals will develop such countermeasures to systems not designed with such foresight. Examples of related technology include modern flash drives which employ encryption, authentication, and anti-tamper technologies, like the IronKey (, Seagate Full Disk Encryption, and others. We will design our system to be user friendly: specifically, it will illustrate exactly what must be done with a given drive. Law enforcement personnel will access and copy password-protected hard disk drives quickly and with confidence in maintaining evidence integrity for later prosecution. We envision an expanded market of state and local investigatory organs which will benefit communities by placing the resource close to more searches in order to obtain timely clues to related criminal efforts. Indeed, such functionality will be needed in the future as more sophisticated criminals use computers to organize their enterprises.
