Waveguide for 100+GHz: Fit in 6" Pipe?

Click For Summary

Discussion Overview

The discussion revolves around the feasibility of fitting a waveguide for 100+GHz frequencies inside a 6-inch pipe. Participants explore the implications of waveguide dimensions, the shape of the waveguide, and the effects of the pipe's internal surface on wave propagation. The conversation includes technical considerations related to microwave waveguides and their applications.

Discussion Character

  • Technical explanation
  • Debate/contested

Main Points Raised

  • Davenn stated that the width of a waveguide should be of the same order of magnitude as the wavelength of the guided wave.
  • Participants inquire about the wavelength of a 100GHz wave and its relevance to fitting a waveguide in a 6-inch pipe.
  • There are questions regarding the impact of the internal surface of a standard six-inch pipe on the propagation of 100GHz waves, noting that waveguides are typically made with polished and plated walls.
  • One participant suggests that a C-band waveguide would likely fit inside a 6-inch pipe, although they acknowledge potential misinterpretation of the original question.
  • Another participant expresses uncertainty about the interpretation of the original post, indicating that it may be difficult to understand the intent behind the question.

Areas of Agreement / Disagreement

Participants express differing interpretations of the original question regarding the fit of a 100GHz waveguide in a 6-inch pipe. There is no consensus on the implications of the pipe's internal surface or the specific dimensions required for the waveguide.

Contextual Notes

The discussion lacks specific calculations or definitions regarding the wavelength of 100GHz waves and the exact dimensions of the waveguide, which may affect the conclusions drawn by participants.

Microwave wave guide
Davenn stated: as a rule of thumb, the width of a wave guide needs to be of the same order of magnitude as the wavelength of the guided wave.
Will a 100+GHz wave guide fit down a 6 inch pipe? what shape would it be? Round, Square, Other?

Do you know what the wavelength of a 100ghz wave is?

And do you know what the effect of the internal surface of 'any old' six inch pipe could have on the propagation of 100GHz waves? Waveguides are usually produced with well polished and plated walls.

At least it would be easier to dent tune. :cool:

The way I read his post was as if he was asking "Will a 100Ghz waveguide fit inside a 6 inch pipe." In that case, yes, it certainly would. A C-band waveguide would probably fit inside of a 6 inch pipe. I could just be reading him wrong though.

really difficult to interpret that one huh
