The utility of Modern high frequency Radars have become degraded due to  innovation in stealth that resulted include unusual shapes that deflect radar waves—like the US B-2 bomber’s “flying wing” design (above)—as well as carbon-based materials and novel paints.  China and Russia have since gotten stealth aircraft of their own, …

Today, modern computing systems are incapable of creating sufficient security protections such that they can be trusted with the most sensitive data while simultaneously being exposed to untrusted data streams.” “Therefore, for the most sensitive computing systems, [the Department of Defense] and commercial industry have in certain places adopted a …

Metamaterials are artificially structured materials designed to control and manipulate physical phenomena such as light and other electromagnetic waves, sound waves and seismic waves in unconventional ways, resulting in exotic behavior that’s not found in nature. This class of micro- and nano-structured artificial media are predicted to be able to protect …

The term, structural electronics (SE), refers to a next-generation based electronics technology, which involves the printing of functional electronic circuitries, across irregular-shaped architectures. SE is expected to replace bulky load-bearing structures within a circuitry with smart electronic components that can conform to complex shapes for ensuring optimum space utilization. SE …

Cryogenics is the study of the production of extremely cold temperatures and is a field of science that looks at what happens when materials, whether metals or gases, are exposed to very low temperatures. The range of temperature associated with cryogenics does tend to vary but is usually associated with …

The mineral scarcity and rising prices of gold, copper and rare earth minerals is creating great interest among many nations for deep ocean mineral mining. The oceans, which cover seventy percent of our earth’s surface are believed to be able to satisfy our need of minerals like gold, copper, silver, …

All over the world Cyber attacks are becoming increasing in number and sophistication. Many organizations in Europe and the US have been crippled by a ransomware attack such as “Petya” ,  WannaCry or WannaCrypt ransomware attack affected more than 230,000 computers in over 150 countries.  Number of incidents such as …

Antennas are our electronic eyes and ears on the world. They play a very important role in mobile networks, satellite communications system, military communications, radars and electronic warfare by transforming a Radiofrequency ( RF) signal, traveling on a conductor, into an electromagnetic wave in free space and vice versa. The …

Brazil is the largest and most important nation in South America, with 35 percent of its total population, 47 percent of its total size, and nearly half of its total GDP. It is the largest and most populous country in the continent; and it benefits from a favourable geographic position, …
