Toroidal ‘Vortex Cannon’ Generates Electromagnetic Pulses for Information Encoding and Probing
Researchers from China, Singapore, and the UK have successfully created toroidal electromagnetic pulses using a horn microwave antenna, dubbed a “vortex cannon.” These doughnut-shaped structures can be used to encode information or study light-matter interactions. The team led by Ren Wang and Yijie Shen employed wideband, radially polarized conical coaxial horn antennas operating between 1.3-10 … Read more
