The security environment of  Japan and the whole region is threatened by expanding military and assertiveness of China and the testing of nuclear weapons and ballistic missiles by North Korea.   Tensions between Japan and China over the Senkaku/Diaoyu Islands dispute have recently increased. Japan’s Defense White Paper released in …

The Defense Department has been pushing hard for digital modernization, but the massive hacking campaign that breached multiple federal government agencies via Solarwinds software has put some of its more nascent efforts at risk — namely software factories. “Yes, this creates a new kind of target for our adversaries. These digital …

The era of hypersonic flight had arrived. Hypersonic refers to aircraft, missiles, rockets, and spacecraft that can reach speeds through the atmosphere faster than Mach 5, which is near 4,000 miles per hour. The hypersonic wind tunnel is used to test flight characteristics in a hypersonic region of Mach number 5 …

Since the development of the field effect transistor in 1920s, the electronics industry has focused on high speed and large capacity devices such as microprocessors and random access memories. However, the recent emergence of personalized and mobile electronics has diversified the research efforts from performance-oriented research to human-friendly topics. Conventional bulky …

Optoelectronic technology is a new technology formed by the combination of photon technology and electronic technology. Optoelectronics is the field of technology concerned with electronic device application to the sourcing, detection and control of light. Optoelectronics is  described as “a device that responds to optical power, emits or modifies optical …

Nuclear power—with its high energy density and low carbon footprint—is a source with which the international community has decades of experience. However, the challenges that come along with the technology have kept it from becoming a more dominant factor in the global energy mix. Geopolitical issues lie at the center …

A classical lens made of plastic or glass has a curved shape that bends the path of incoming light toward a single focal point on a piece of photographic film or an electronic sensor. This is because light travels faster through the thinner glass at the edges of the lens …

Over the past few decades, advances in electronic sensors, communications technology, and guided weapons may have fundamentally transformed the nature of air combat.  One of critical technologies was superior situational awareness (SA) when a pilot has a better understanding of the position of all relevant aircraft and their activities in …

Smart materials or Active materials or Functional materials are designed materials that have diverse, dynamic features that enable them to adapt to the environment. They have one or more properties that can be significantly changed in a controlled fashion by external stimuli, the stimulus and response may be mechanical, electrical, …
