The rapid evolution of millimetre-wave (MMW) imaging and radar systems is transforming applications across security, remote sensing, and non-destructive testing. These systems utilise electromagnetic ...

The Chinese military claims it has developed a new radar-defeating coating that can hide targets from anti-stealth radar. The coating can absorb low-frequency electromagnetic waves (EM) and is only ...

When we look at the weather, radar plays a big role in helping us understand if it's raining or snowing. Here's how it works: Radar works by sending out radio waves that travel through the air. When ...

Radar guns have become more sophisticated, utilizing various frequencies and modulation techniques, making it challenging for radar detectors to keep up. The very essence of the effectiveness of the ...

As our quest for knowledge about our planet grows, so does the need for novel technologies to offer new insight into the changing face of Earth. Researchers are excited about the potential of a new ...

The U.S. has spent half again as much (nearly $3 billion) on radar as on atomic bombs. As a military threat, either in combination with atomic explosives or as a countermeasure, radar is probably as ...

A radar screen is shown in the generic image. In a future that has self-driving cars and super-fast broadband even in the planet’s most remote places, private companies are going to need a whole lot ...

AMES, Iowa – Iowa State University engineers have developed a new flexible, stretchable and tunable “meta-skin” that uses rows of small, liquid-metal devices to cloak an object from the sharp eyes of ...

An invisibility cloak is still the holy grail of stealth, but FibreCoat’s radar-absorbing material is close: the lightweight plates shield fighter jets, drones, and satellites from being seen by radar ...
