Funny how this page is so littered with 'disputed' tags when nearly every single aspect of physics' factual accuracy is disputed. Being wrong is just another step on the path to being right. —Preceding unsigned comment added by 67.98.176.66 (talk) 20:45, 7 February 2011 (UTC)

Needs beirf explanation of modes

An early figure refers to TE31 mode and there's later mention of TE01. While I'm accustomed to seeing this terminology, what does it actually /mean/? A brief explanation could usefully appear at some point in the article. MarkMLl (talk) 06:51, 8 June 2023 (UTC)

Modes are described in Mode (electromagnetism), but it doesn't seem to get to the numbers part. Should be fixed there, before here, though. Gah4 (talk) 20:52, 8 June 2023 (UTC)

directionality

The article says ... guides waves by restricting the transmission of energy to one direction. Most waveguides are bidirectional, though some work different in the two directions. Especially there is a directional coupler. Most of the time, though, they are bidirectional. Gah4 (talk) 05:24, 6 September 2023 (UTC)

Agreed. And then there are two dimensional waveguides. And waveguides that do not completely confine the waves. And intentionally leaky waveguides. Constant314 (talk) 09:08, 6 September 2023 (UTC)

So, I think it wants something like one dimension, which would allow for two directions. I suppose there are 2D waveguides, and those could have a section. Gah4 (talk) 13:03, 6 September 2023 (UTC)

The power planes of a circuit board are 2D waveguides. A current filament between the planes produces a cylindrically expanding wave. Constant314 (talk) 15:07, 6 September 2023 (UTC)

I think of them as 2D transmission lines, but then transmission lines are a subset of waveguides. And especially, for the case you indicate, radial transmission lines. Some people only consider hollow waveguides for a waveguide article. I think this one doesn't, but would have to read carefully to see. Gah4 (talk) 20:30, 7 September 2023 (UTC)

They also support higher order modes. Constant314 (talk) 03:01, 8 September 2023 (UTC)

Unusual waveguide structures

A recent edit archives discussion of the Waveguide rotary joint. Reminds me that I know about waveguide vacuum valves, that can close off a waveguide when needed, and yet allow full power (25MW, 0.1% duty cycle) when open. I don't think that goes in this article, but maybe one article for unusual waveguide structures or devices would be worth doing. Gah4 (talk) 20:35, 7 September 2023 (UTC)

Can we remove template: "This section needs additional citations for verification"

I added many additional citations to Impedance matching section. Is there agreement to remove template: This section needs additional citations for verification? If there is agreement, please remove the template. Thanks ~~ TMM53 (talk) 21:05, 1 January 2024 (UTC)

• Done. Thanks for the improvements.
