Reference page
[edit]In the references, the "Electromagnetic Theory for Microwaves and Optoelectronics" By Zhang & lee, which is cited for the LSE and LSM modes, is found in page 322 rather than 294 as written here.

- Not according to the the contents section, and here's page 294 if gbooks will serve it to you. Maybe you are looking at a different edition.. SpinningSpark 14:39, 25 March 2019 (UTC)
The Waveguide article mentions modes, including ones like TE1,3, but doesn't explain at all the numbers. And they aren't explained here, either. It seems that this is where they should be explained first, and linked from waveguide. Gah4 (talk) 20:56, 8 June 2023 (UTC)
Move to "Mode (wave)" or "Wave mode" or "Waveguide mode"?
[edit]Acoustic modes are not mentioned and AFAICT modes are solutions of the wave equation with (finite) boundary conditions (guides). I suppose we could have "Mode (acoustic)" but that would obscure the commonality. If we moved this article to "Mode (wave)" or "Wave mode" or "Waveguide mode", then both could be covered and the commonality discussed.
- "This same wave equation occurs (although, generally also as an approximation) in a variety of other contexts: electromagnetic theory, gravity waves in shallow water, dilatational and shear elastic waves in solids, transverse vibrations in stretched membranes, Alfvén waves in magnetohydrodynamics, pressure surges in liquid-filled tubes with elastic walls, e.g., blood vessels, and electromagnetic transmission lines."

- A closed resonator has modes that are not waveguide modes. Modes spewing out of an aperture are not waveguide modes. Waveguide (electromagnetic) mode is a subtopic of Mode (electromagnetism).
- Perhaps create Waveguide modes as a subpage to this page? As Mode (electromagnetism)/Waveguide modes. Constant314 (talk) 01:46, 8 September 2024 (UTC)
- OK thanks, so forget "waveguide mode". I was trying generalize, to group wave "modes" across electromagnetic/acoustic etc. per the Pierce quote above. Johnjbarton (talk) 03:09, 8 September 2024 (UTC)
