Fiber optics, or optical fibers, are long, thin strands of carefully drawn glass about the diameter of a human hair. These strands are arranged in bundles called optical cables. We rely on them to transmit light signals over long distances. Optical fibers typically include a glass structure called core …

Speech Translation is the process by which conversational spoken phrases are instantly translated and spoken aloud in a second language. A speech translation system would typically integrate the following three software technologies: automatic speech recognition (ASR), machine translation (MT) and voice synthesis (TTS). Fast, accurate speech-to-speech translation can globalize the free …

The Department of Defense (DoD) is one of many government agencies that operates globally and is in constant contact with diverse cultures. Communicative understanding, not simply of local languages but also of social customs and cultural backgrounds, lies at the heart of Civil Affairs and Military Information Support Operations activities. …

Quantum computers could undermine almost all of the encryption protocols that we use today. Though quantum computers are still quite some way from being practical, usable machines, once they become so, we could be looking at a whole new world when it comes to online privacy — one in which …
Read More »AI enabled Intelligent Satellite Networks
Satellite communication can provide many benefits and complement terrestrial networks. They can provide service continuity, to provide network access over uncovered and under-covered areas. They can provide backup or service ubiquity, to ameliorate the network availability in cases of temporary outage or destruction of a ground network due to disasters. …
Read More »Dynamic metasurfaces including Liquid crystal metasurfaces allow tuning of metasurface functionality also after fabrication.
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 illumination source employs different technologies, ranging from lamps to semiconductor light emitting diodes (LEDs) or lasers. The lamp, while straight-forward, is broad-band, bulky, and generally inefficient. The main wavelengths of interest for illumination are around 808nm, 976m, 1064nm, and 1550nm. The 808nm region offers the best responsivity for …

The race to conquer the quantum domain is among the most fiercely competitive in today’s world of technology. One important quantum technology is Quantum key distribution (QKD), that establishes highly secure keys between distant parties by using single photons to transmit each bit of the key. Quantum cryptography is unbreakable …

Cyber physical systems (CPS) are instrumental to current and future Department of Defense (DoD) mission needs – unmanned vehicles, weapon systems, and mission platforms are all examples of military-relevant CPS. These systems and platforms integrate cyber and physical subsystems, and the enormous complexity of the resulting CPS has made their …

Systems like GPS, Russia’s GLONASS, China’s BeiDou, and Europe’s Galileo systems are Global Satellite Navigation Systems (GNSS) that provides real-time positioning, navigation and timing (PNT) data. The worldwide Global Positioning System (GPS), created in the late 1980s, has evolved to become an essential part of life for nearly every person on …
