Research into ionospheric wave generation and modulation has significantly enhanced our understanding of the upper atmosphere’s dynamic behaviour. Ionospheric waves arise from the interplay between ...

Most often ultrasonic transducers are used for distance measurements, and in the DIY world, usually as a way for robots to detect obstacles. But for a weekend project, [Vinod.S] took the ultrasonic ...

Electromagnetic energy in the terahertz region of the spectrum – nominally 300 GHz/0.3 THz to 10 THz, although some consider it to start at 100 GHz/0.1 THz – presents a technical dilemma. On one hand, ...

The elderly often complain about hearing difficulties, especially when several people are talking all at once. Researchers at the Max Planck Institute for Cognitive and Brain Sciences in Leipzig have ...

When engineers hear the phrase LiDAR, an acronym for Light Detection and Ranging, they generally think of time-of-flight (ToF) systems. ToF LiDAR is widely used in automotive and robotic applications ...

Pinpointing the minimum and maximum transient noise bandwidth for a transient noise simulation is a non-trivial task. But these algorithms can help ease the challenge and minimize simulation time.

Synthetic-aperture radar, in which a moving radar is used to simulate a very large antenna and obtain high-resolution images, is typically not the stuff of hobbyists. Nobody told that to [Henrik ...

Researchers have devised a novel circuit design that enables precise control of computing with magnetic waves -- with no electricity needed. The advance takes a step toward practical magnetic-based ...

The following is excerpted from Chapter 3: Radio Basics for UHF RFID from the Book, The RF in RFID: Passive UHF RFID in Practice by Daniel M. Dobkin. Order a copy of The RF in RFID: Passive UHF RFID ...
