High frequency high power alternating current

Click For Summary
SUMMARY

High frequency high power alternating current requires careful consideration of transmission methods. Regular wire may not be suitable for efficient transmission; instead, waveguides are recommended when the cross-sectional dimension is at least half the wavelength of the signal. The choice between waveguides and other mediums like coaxial cables or twisted pairs depends on the specific frequency and power levels involved. For detailed information, refer to authoritative electromagnetic resources.

PREREQUISITES
  • Understanding of electromagnetic wave propagation

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:
