(42S) FRECC - Cutoff frequency equations for circular waveguide (TEmn or TMmn) - Emilio Abud Filho - 10-26-2022 06:53 PM
Dear All
Please, find attached a simple code and documentation for solving Cutoff Frequency for circular waveguide, considering TEmn or TMmn modes; (to be used with "HP Solver" feature).
Order range: 0≤m≤4 and 1≤n≤4
Since this is my first program submission, I would appreciate your feedbacks, in order to improve my way of doing the documentation.
Attachments:
- Program documentation, including example, math equations, how to use explanations, source code, etc; (xlsx and pdf)
- PLmn and Pmn matrices as variables (xls)
- RAW format file (zip)
Code:

What he really meant is to use the # button in the toolbar:

Dear Pinkman
Now I see!!!
Sorry for my lack of understanding!
Thank you very much for your explanation!
I will proceed correctly in my next program submission!
Warm regards!

Really nice in-line graphics!

Dear All
I have updated the technical documentation, (there was some typing and grammar errors...).
Please, find the revised documentation (v1.04), attached to the original post.
The program itself (.raw) and matrices (xlsx), were good, and remain the same.
I am sorry for my typing and grammar mistakes...
Warm regards
