Scientists create novel approach to control energy waves in 4D

Not sure you are managing to be any more clear.

I am sure you are visualizing something sensible but reading that, to me, felt as ambiguous as the article.

Can you use a specific example with an actual physical 3D + extra dimension situation?

For instance, an actual example of a 4D-to-3D situation is the mapping of 3D space + 1D time to a 3D RGB color space, when representing the visual experience of a flying formation of LED drones.

Something that concrete?

think of corrugated metal. sound waves and heat will travel slower in the wavy direction than in the straight direction. you can stamp some more complicated pattern onto a piece of metal to control how sound waves travel through it. like a sound circuit. (eg. passive sound canceling metal panels. things like that)

you could come up with some material that naturaly has those kinds of properties without being wavy. but mathematically its the same thing.
