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

In summary, Davenn stated that the width of a wave guide should be similar to the wavelength of the guided wave. It is possible for a 100+GHz wave guide to fit inside a 6 inch pipe, but the shape of the wave guide would depend on the internal surface of the pipe. The effect of this surface on the propagation of 100GHz waves is usually minimized through the use of well polished and plated walls. However, it may be easier to dent tune in this case.

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
 

1. What is a waveguide and how does it work?

A waveguide is a type of transmission line used in high-frequency electronic systems to guide electromagnetic waves from one point to another. It consists of a hollow metal pipe with a specific cross-sectional shape that allows for the propagation of electromagnetic waves. It works by confining the waves within the pipe, preventing them from spreading out and losing energy.

2. Why is a waveguide necessary for frequencies above 100GHz?

At higher frequencies, traditional transmission lines such as coaxial cables become less efficient and more prone to signal loss. A waveguide, on the other hand, is designed specifically for high-frequency applications and has lower losses, making it the preferred choice for frequencies above 100GHz.

3. What is the significance of fitting a 100+GHz waveguide in a 6" pipe?

The size of the waveguide is directly related to its operating frequency. As the frequency increases, the size of the waveguide decreases. Fitting a 100+GHz waveguide in a 6" pipe means that it is highly miniaturized, making it suitable for compact and portable high-frequency electronic systems.

4. What are some common applications of a waveguide for 100+GHz frequencies?

Waveguides for 100+GHz frequencies are commonly used in high-frequency communication systems, radar systems, and satellite communications. They are also used in research and scientific experiments that require precise and efficient transmission of high-frequency signals.

5. Are there any limitations to using a waveguide for 100+GHz frequencies?

One limitation of using a waveguide for 100+GHz frequencies is the high cost of manufacturing and maintaining them. They also have a limited bandwidth compared to other transmission lines, which may restrict their use in certain applications. Additionally, the size and weight of the waveguide may become a limitation in certain portable systems.
