DARPA’s Blue Wolf developed fast, efficient underwater vehicles (UUVs) with energy, hydrodynamic lift, and drag-reduction technology breakthroughs

DARpabluewolf

Unmanned underwater vehicles (UUVs) have inherent operational and tactical advantages such as stealth and surprise. UUV size, weight and volume are constrained by the handling, launch and recovery systems on their host platforms. Mission performance typically sets the range, endurance,…...

DARPA Hydra developed a distributed undersea network of UUVs and UAVs able to operate independently for weeks or months

Hydra Graphic scaled

Today’s naval forces rely primarily on highly capable multifunctional manned platforms, such as ships and submarines. Even the most advanced vessel, however, can only be in one place at a time, making the ability to respond increasingly dependent on being…...

Muography employs cosmic ray particles Muons, to detect shielded nuclear contraband, to objects deeply buried up to thousands of meters below the earth’s surface

muon

Muons are subatomic particles that behave a lot like electrons but are around 200 times heavier. As the US Department of Energy explains, “Muons created in the atmosphere constantly hit every inch of the Earth’s surface and pass through almost…...

“Trion” instead of electron will play a key role in Future electronics and Quantum information transmission

trion

Trions are what scientists call “quasiparticles,” bundles of energy, electric charge and spin that zoom around inside semiconductors.   Trions were first observed in quantum wells in 1993 and shortly thereafter in GaAs-AlGaAs quantum wells. Trions were were predicted and…...

Polarization-based imaging systems or cameras enhance machine vision, autonomous vehicle navigation, facial recognition, and military target detection

polarization sensitive camera

Humans view the intensity of light as the various colors of the spectrum. Characteristics of light include amplitude (intensity), frequency (color), polarization, and coherence. The human eye has cone cells, that correspond reflected light from objects into colors which range…...
