In communication applications like the internet, the most simple form of optical communication is with a single fiber consisting of a single wavelength laser TX/RX scheme. In fiber-optic communications, wavelength-division multiplexing (WDM) is a technology that multiplexes a number of optical carrier signals onto a single optical fiber by using different …

One of biggest threat to the deployed aerospace and defense electronics systems is radiation. Long term exposure of astronauts to radiation is equally challenging. This force can occur naturally in space and at high altitudes on Earth, or can come in massive doses from the detonation of nuclear weapons. Deep-space and …

Robotics has made significant progress, since its first deployment as an industrial robot more than 50 years ago. Robots are now days being used extensively in manufacturing, services, healthcare/medical, defense, and space. They have enhanced safety of humans from dangerous tasks, improved the productivity and the quality of life. In …

Some 1 million people suffer traumatic brain injuries annually. Concussion can cause inner ear damage that can cause dizziness, anxiety, depression, moodiness, balance problems and irritability, said Elizabeth Kirkpatrick, the physical therapist for the Fort Drum Traumatic Brain Injury Clinic. The three different forms of TBI—severe, moderate, and mild—all manifest …

Most spacecraft propulsion concepts can be classified into two categories: chemical and electric. Chemical propulsion relies on chemical reactions and can produce high thrust, but requires a large amount of fuel. Electric propulsion uses electromagnetic fields to accelerate ionized gases and is very fuel-efficient, but produces small amounts of thrust …

Energy is a critical enabling component of military operations and demand for it will continue to increase over time. In particular, energy usage during contingency operations will likely increase significantly over the next few decades. The modern operational space has amplified the need for alternative energy sources to enable mobility …

Consumer electronics constitute a rapidly increasing source of waste. Cell phones, tablets and the like are typically made of non-renewable, non-biodegradable, partly environmentally toxic materials. A report from United Nations University (UNU) found that the world produced 41.8 million metric tons of e-waste in 2014 – an amount that would fill …

When body armor and bulletproof vests reach the end of their service life, law enforcement and military organizations must dispose of ballistic materials in accordance with National Institute of Justice (NIJ) regulations. The National Institute of Justice (NIJ) has provided a publication, Guide to Body Armor, which lays out standards …

Quantum technology (QT) applies quantum mechanical properties such as quantum entanglement, quantum superposition, and No-cloning theorem to quantum systems such as atoms, ions, electrons, photons, or molecules. Quantum bit is the basic unit of quantum information. Whereas in a classical system, a bit is either in one state or the another. …
