Get the intricate details and understand the larger picture of some of the most unique materials to recently emerge and see what strides are being made to incorporate them into military use. Sessions include overviews of novel materials such as:
Light-weight ultrastrong materials are of paramount importance for the Department of Defense. Hierarchical organization of nanoscale materials can provide reliable opportunity for the development of next generation materials that are valuable for a variety of military applications. This session will address the high loading of nanoscale building blocks for ultrastrong composite materials, manufacture of light-weight transparent armor materials, enhancement techniques for body armor, and development of multifunctional (smart) materials for improved soldier safety and survivability.

Metamaterials open unprecedented opportunities for refractive index engineering and enable highly unusual regimes of nonlinear light-matter interactions. Availability of low-loss, reconfigurable and broadband metamaterials at optical frequencies is essential for the realization of their applications ranging from military imaging and sensors, with improved resolution and sensitivity to communications and optical stealth technology. Many of these functionalities benefit from a combination of unique linear and nonlinear properties of these materials. This session will focus on the design, modeling, fabrication, and applications of nanostructured nonlinear metamaterials.

The possibility of cloaking an object from detection by electromagnetic waves has recently become a topic of considerable interest. The design of a cloak uses transformation optics, in which a conformal coordinate transformation is applied to Maxwell's equations to obtain a spatially distributed set of constitutive parameters that define the cloak. Here, we present an experimental realization of a cloak design that conceals a perturbation on a flat conducting plane, under which an object can be hidden.
To match the complex spatial distribution of the required constitutive parameters, we constructed a metamaterial consisting of thousands of elements, the geometry of each element determined by an automated design process. The ground-plane cloak can be realized with the use of nonresonant metamaterial elements, resulting in a structure having a broad operational bandwidth (covering the range of 13 to 16 gigahertz in our experiment) and exhibiting extremely low loss. Our experimental results indicate that this type of cloak should scale well toward optical wavelengths.
As the Navy, Marine Corps and Army have explored lighter, smaller and more powerful autonomous energy generation strategies aligned with new battlespace parameters, SBIR has emerged as a principal test-bed for research, development and transition of advanced materials supporting these stand-alone energy generation devices. SBIR's ability to attract cutting-edge material solution providers, and partner them with large firm production capability and acquisition program needs, is drawing increased attention from government and industry decision makers. This workshop samples resonant technologies and key technology transition stream players.
