GaN is a semiconductor material that can amplify high power radio frequency signals efficiently at microwave frequencies  to enhance  a system’s range. Therefore it has become the technology of choice for high-RF power applications that require the transmission of signals over long distances such as EW, radar, base stations and satellite communications. The advantages of GaN-based devices stems largely from the attractive intrinsic physical properties of the material. The material …

3D printing or additive manufacturing is ongoing revolution in manufacturing with its potential to fabricate any complex object and is being utilized from aerospace components to human organs, textiles, metals, buildings and even food. Additive manufacturing, is defined by ASTM International as the process of joining materials together, layer by …

The conditions under which our Armed Forces conduct operations are rapidly changing with the spread of blogs, social networking sites, and media‐sharing technology (such as YouTube), and further accelerated by the proliferation of mobile technology. Changes to the nature of conflict resulting from the use of social media are likely to …
