Metamaterials and photonic crystals are engineered composites that exhibit novel and interesting properties not found using ordinary materials. They have been shown to allow extraordinary control over the electromagnetic field, including molding the flow of energy, amplitude profile of the field, phase of the waves, intermodal coupling, and more. To achieve such control, a set of tools and procedu ...

The research objective is to develop a tunable spatially-varying photonic crystal (SVPC) to achieve the optical propagation properties (reflection and transmission) of the light through the designed structure for the visible and near IR-bands. The light from this SVPC will be able to focus and bend as a function of the spatial variation of the refractive index, input angle, and state of polarizati ...

UbiHere, a Columbus Ohio based small business, has developed, in conjunction with The Ohio State University, a unique highly capable low-cost system to address the known issues with GPS denied tracking of assets, equipment or people in indoor and outdoor operating environments. UbiHere’s commercial system is comprised of an application specific electronics tag, designed by the company, whic ...

The objectives of this Phase-II research effort is focused on transitioning noninvasive diagnostic techniques based on ultrafast lasers for characterizing nanoenergetic materials and their performance in rocket engine environments. Through the use of ultrafast laser imaging and spectroscopy, it is possible to isolate and characterize each physical process from initiation through energy release an ...

Spectral Energies proposes to design a multisensory diagnostic suite for measurements within elevated-pressure RDEs. This sensor will utilize tunable-laser absorption spectroscopy to measure temperature, pressure and H2O concentrations in the annulus of a rocket-RDE and background-oriented schlieren imaging system for flow density gradient imaging to provide time resolved information about the sho ...

High-speed and reliable tactical communications have empowered the Air Force with overwhelming information superiority, and control of the battlespace. However, the effectiveness of such systems has been impacted by the increasingly congested and contested spectral environment, compounded by the reliance on half-duplex systems. The latter rely on time- or frequency-division to separate transmit an ...

Locating objects that vibrate is a way to discern potential threats and locate targets. However, current vibrometry technology typically measures only the global vibration of target and cannot create an extended spatial measurement of the vibration profile of the target. These solutions cannot identify what the target is, nor can they locate potential weak spots on the target, because they lack sp ...

The imaging vibrometer development will be based on a representative Directed Energy (DE) aperture assumed to be 30 cm. This effort will provide both DE and Combat IDentification (CID), modes for relative short range DE operations, and an ISR Combat IDentification (CID) mode for operation at extended range. A combination of analytic derivations and wave optics simulations will be used to define a ...

This Small Business Technology Transfer Phase I project will develop ultradense, low-power plasmonic integration components and devices for on-chip manipulation and processing of optical signals. Both passive and active components will be studied. Detailed performance predictions will be obtained through finite element modeling (FEM) of the harmonic Maxwell’s equations. The FEM provides detai ...
