High frequency high power alternating current

  1. Aug 6, 2006 #1
    Hi,

    When you have a high frequency high power alternating current, Can you use a regular wire to transmit the current or do you have to use a waveguide? Or some kind of combination?

    Thanks.

    Whats your definition of "high frequency high power"? I would lookup waveguides in a book. Any decent EM book will have your answer.

    Waveguides must be at least a half-wavelength in cross-sectional dimension in order to be efficient. That is the main thing that defines whether you would use a waveguide or a coax (or twisted pair) transfer medium. Check out this writeup from wikipedia:
