In this document we examine recent developments in double negative materials (DNM) or negative index of refraction materials (NIR) and
consider their potential military applications. These materials are artificially engineered, composite structures that provide extraordinary
responses to electromagnetic (EM) waves in general. These materials are important because they allow us to control light (or EM waves)
in ways not previously possible. Because these metamaterials exhibit a unique ability to bend and focus light in ways no other
conventional materials can, they hold great potential for enabling a number of innovative lens and antenna structures. Searching for
smaller, lighter, and conformal components and devices for radar and communication applications, researchers have increasingly turned
to these metamaterials. It is expected that research will lead to innovative designs in optical instrumentation, sub wavelength resolution,
reduction of friction in MEMS, novel approaches to beam steering, novel approaches for integrating optics with semiconductor electronics
and others. Many IDA projects could benefit from the knowledge obtained as a result of this study.
