Quantum sensors using Rydberg atoms enable ultrasensitive and ultrawideband electric field sensors, communication receivers from VLF to Terahertz

Quantum sensing uses some nonintuitive properties of nature to measure things like time, magnetic fields, gravity, or acceleration. Quantum sensing has become a distinct and rapidly growing branch of research within the area of quantum science and technology, with the most common platforms being spin qubits, trapped ions and flux qubits. …

US Navy gives thrust to development of Electromagnetic Warfare systems

All modern forces depend on unimpeded access to, and use of, the EM spectrum in conducting military operations. Therefore, there is a requirement to gain and maintain an advantage in the electromagnetic spectrum by countering adversary’s systems and protecting one’s own systems. Thus the EM spectrum can no longer be …

Rectenna or rectifying antenna critical technology for wireless power systems, powering military drones, and receiving solar power from satellites

Over the past two decades, many wireless systems have been developed and widely used around the world. The most important examples are cellular mobile radio and Wi-Fi systems. Just like radio and television broadcasting systems, they radiate electromagnetic waves/energy into the air but a large amount of the energy is …

Ultrasound sensors becoming cheap, miniaturized and ultrasensitive leading to wide employment in automotive, healthcare, industrial, and electronics.

As the name indicates, ultrasonic sensors measure distance by using ultrasonic waves. The basic working principle of these sensors is based on echolocation, which involves transmission of ultrasonic waves to the target object, which reflects it back to the source after receiving the initial wave. The ultrasonic sensors detect the exact …

Active and Passive Millimeter Wave imaging systems employed for security screening at the airports and finding landmines

Electromagnetic waves in the millimeter-wave band  (with frequencies between 30 and 300 GHz, or wavelengths between 10 and 1.0 mm) have attractive characteristics. One of their features is the wider usable frequency band compared with waves in the microwave band or lower bands. Another feature of using the millimeter-wave band is the fact …

New Magneto resistive materials enable ultrasensitive magnetic field sensors, brain-like computing chips and 3D magnetic memory

Magneto resistor is a type of resistor whose resistance changes when an external magnetic field is applied. In other words, the flow of electric current through the magneto resistor changes when an external magnetic field is applied to it.   Magnetic field is the region present around a magnetic object …

Rising employment of millimetre or EHF based radars, communications and seekers by Military creating new electronic warfare challenges

The advancement of Sensors, Communications and Radars have given rise to Electronic Warfare, which encompasses, in all battle phases, military actions involving the use of EM energy to determine, exploit, reduce or prevent hostile use of EM spectrum and the actions, which retain friendly use of the EM spectrum. The …

High-Temperature Electronics technologies for extreme environment like Geothermal vents, aircraft engines, gas turbines and hypersonic structures.

“Electronics have dramatically changed the way we live, conduct business, communicate, and educate. Visions of the future foretell of ubiquitous computing and sensing. However, the environments in which electronics can reliably operate are limited. In consumer applications, typical operating temperatures range from -40° to 85°C. The “wider” military temperature range …
