Firstly\, he contrasted the theoretical understanding that con ductors transmitting DC signals do not form a waveguide\, due to the decou pled nature of static electric and magnetic fields\, with the practical re ality that DC signals require finite turn-on and turn-off times\, which in volve transient states. He then presented the core argument that since the se transient states rely on electromagnetic wave propagation\, the DC sign al itself must also be sustained by wave propagation. Finally\, he shared experimental results that explicitly demonstrate electromagnetic wave prop agation during DC signal switching\, as well as analytical studies based o n transmission line theory proving that electromagnetic waves persist even in the DC steady state. He concluded that\, in practice\, two pieces of c onductor behave as a waveguide when transmitting DC signals\, as the elect ric and magnetic fields remain coupled.\n\nSpeaker(s): Mingyu Lu \n\nCheng du\, Sichuan\, China LOCATION:Chengdu\, Sichuan\, China ORGANIZER:xiongjiang@uestc.edu.cn SEQUENCE:10 SUMMARY:Is DC Power Transmitted by Electromagnetic Waves?
