The film explains the concept of electromagnetic waves, particularly focusing on their applications in radar, radio, and television. It describes how a crystal set functions as a simple radio receiver ...

The systematic investigation of the properties and characteristics of these very short waves was taken up in view of the advantages which they seemed to offer in the field of practical radio ...

Rumor - The Zimbabwean inventor Sani Chumo Chumo (Sangulani Maxwell Chikumbutso) developed an electric car that operates without recharging, drawing energy from the air through radio frequency and ...

London’s Heathrow Airport, one of the world’s busiest, will be shut all day Friday due to a “significant power outage” as a ...

The author describes powerful and sophisticated analytic and numerical methods to solve electromagnetic problems for complex media and geometry as well. Problems are presented as realistic models of ...

The research will be presented at the IEEE International Solid-State Circuits Conference (ISSCC 2025). Terahertz waves sit on the electromagnetic spectrum between radio waves and infrared light. Their ...

Scientists have revealed a hidden trigger of lightning that could resolve a centuries-old weather mystery. Earth is struck by ...

which leads to the interruption of radio communication. In this article, Using the Bhatnagar–Gross–Krook (BGK) collision model, this study calculates the transmission coefficient of electromagnetic ...

Radio astronomers can study emissions from gas giant planets, blasts from the hearts of galaxies, or even precisely ticking ...

Electromagnetic radiation is the general term for the more familiar light and radio waves, but also includes gamma rays, x rays, ultraviolet rays, and infrared. All of these forms of electromagnetic ...

Terahertz waves sit on the electromagnetic spectrum between radio waves and infrared light. Their higher frequencies enable them to carry more information per second than radio waves, while they ...

IT is now well known that electric waves having a wave-length of less than about 8 metres are of little use for long-distance radio communication, owing to X the apparent inability of the ...
