Conforming a 3d object to another 3d surface.
Sorry I'll make myself more clear.
I want to imprint this pattern
onto this pattern
and I want the first pattern to follow the contours of the second pattern.
You can use the new emboss tool! there is a great video I'll try to find it - showing how to make a knurled pattern using the emboss tool + here is a quick try using the sheet metal but it is not as perpendicular
The difficulty will be the calculation to make something appear as waves on waves take a look:
My model is not "formed" but constructed with a little math to get the angles right. I left the cylinder and the layers of the pattern as separate bodies. You can combine them into one unit using the combine command if desired. You can follow the time line to see how it is done. Model is attached.

I forgot the screen capture of the model. Here it is. You can download it from my previous post.

I am watching with interest how this develops.
What @YoavFriedlander ran into is that the surface pattern distorts. It is stretched on top of the waves and as it travels down into The valley it is compressed. That will be difficult to eliminate. It might visually be less obvious if the surface pattern is a lot smaller (higher in frequency, lower in amplitude) than the wave surface it is supposed to follow.
@TrippyLighting yes - I am still trying to figure out if such symmetry can exist - I bet there is a way and my brain can't overcome the obstacle - something about the above cylinder in previous comment by @jhackney1972 gives me hope but I suspect that the problem will start in the transition between outer facing curve and inner facing curve. I made a more elaborate demonstration of the problem you mentioned previously via the Sheet metal environment:
Here is a progress based on @jhackney1972 cylinder
The main issue that if I start with a circle divided to 36 sections and create 36 tangent circles around it the inner circle creates an angle of 12.1 degrees vs. 10deg on the outside which means it looks nice but it is not symmetric!:) I think my next step is to figure out the circle that connects the center of all circles! maybe there will be a solve to the tension ?
It looks nice - but it is not absolute correct
Also I realize it is better to use uneven number of circles ! which even makes life harder 😕
Take a look at the Screencast. The angle for the original sketch is 360 degrees divided by the number of instances in my circular pattern.

I would really enjoy getting into some of your models to see what you are thinking and creating but you have a habit or posting screen captures but no attached models. I am sure the original post would like to see your models attempts also.

Here is the same pattern created on a sheet metal curve. It will unfold and refold using the timeline and it will even create a flat pattern with a big red box in the timeline. Plus it is a pain to do since you must use Extrude - Join for each row which means you have to duplicate your pattern sketch over and over. Model attached.

I've been trying to do what jhackney1972 did but I continuously fail.
I'm trying to get the waves to be 0.5mm in height, length, and width and I want them in rows of 40 on a 4 inch cylinder but I can never get the waves to line up properly.
Clearly my math is failing me somewhere.
There is a gap between each one and I'm a bit clueless on where I went wrong.
The dimensions you give do not seem correct. A 0.5 mm sketch is an extremely small sketch plus you are mixing units when you say your cylinder is 4 in, diameter or radius you did not say, The measure shown in your screen capture is 13.21 diameter which does not match anything. In the sketch below, which is one segment of my model, note the bounding lines go to center. I also originally dimensioned the curves at 1" to originally get a general size but then removed it to let the segment angle control their size. All the curves have an equal constraint applied. The construction circle is just a floating guide circle for the curve centers. The angle of the segment is the number of my, later to be applied, circular pattern of 21 divided into 360. If you attach your model, the forum users can help you out for sure.
