If you’ve ever used Bluetooth, Wi-Fi, or got directions from Google Maps, please take a moment to thank Hedy Lamarr. The Austrian-American actress, once called “the most beautiful woman in the world”, was born in Austria in 1914, and in 1937 she went to Hollywood, where she starred in highly acclaimed films such as Algiers

Abstract The IEEE and ICNIRP have set the maximum permissible exposure for an instantaneous peak electric field of 100 kV/m. However, no reason was given for this limitation. A new exposure system is designed through a detailed process of analytical analysis, numerical modeling and prototype testing. The system consists of a cylindrical re-entrant resonant cavity
Researchers have developed a new metasurface-based antenna, which represents an important step in making it convenient to collect energy from radio waves, such as those in cellular networks or Bluetooth connections. This technology could potentially offer wireless power to sensors, LEDs and other simple devices with low power requirements. “By eliminating cable connections and batteries,
The demand for flexible and inexpensive wireless communications and applications has sparked interest in innovation in wireless energy collection. For example, scientists were able to use organic material for a new semiconductor design for radio frequency circuits. Notably, organic semiconductors have applicability in 5G applications, according to international scientists led by King Abdullah University of

The idea of ​​the Doherty amplifier is not new: this modified class-B radio frequency power amplifier (RF PA) configuration was designed by William H. Doherty of Bell Telephone Laboratories Inc. in 1936, in the early days of the high-power vacuum. tube amplifier (Fig. 1 and References 1 to 3). Since then, it has been used

The energy harvest is showing a lot because new ways are being sought to generate electricity. One technology involves a common source: radio waves. Researchers at the University of South Florida are trying to extract energy from radio waves using synthetic materials called metamaterials, which exhibit properties not normally found in natural materials and are
