Algorithm Predicts How Electromagnetic Waves Interact with Materials at the Smallest Scales

Magnetic materials can attract or repel each other based on their polar orientation — positive and negative ends attract each other, while two positives or two negatives repel. When an electromagnetic signal like a radio wave passes through such...

Q&A: NASA's Dr. Mahmooda Sultana Makes Multifunctional Sensors

Dr. Sultana won funding to advance a nanomaterial-based detector platform that can sense environmental parameters from minute concentrations of target gases and vapors, to atmospheric pressure and temperature, and then transmit that data via a wireless antenna — all from the same 3...

Multiplexing of Wireless Surface Acoustic Wave Sensors

The traditional approach for wireless sensors involves interrogators that communicate with each other (i.e., the two boxes “talk” to each other). In contrast, surface acoustic wave...

Quantum Radio Aids Communications and Mapping

GPS signals do not penetrate very deeply or at all in water, soil, or building walls, and therefore can’t be used by submarines or in underground activities such as surveying mines. GPS also...

System Enables Direct Data Transmission Between Underwater and Airborne Devices

Today, underwater sensors cannot share data with those on land, as both use different wireless signals that only work in their respective mediums. Radio signals that travel through air die very rapidly in water. Acoustic signals, or sonar, sent by underwater devices...

Gated Chopper Integrator (GCI)

Microvolt-level signals require gains of at least a thousand. Offsets and noise in the amplifier chain will be amplified by the same amount, which can saturate the amplifier or swamp the signal so it is not resolvable. Other methods use chopping and/or autozero techniques to lower the offset and noise. The key...
