I'm glad to see you shed that nonsense about hydraulics. As you
understood that topic far less than RF (which is in itself on very
shaky ground), it wouldn't have done to poison the well.

This poor understanding is quite obvious by your last comment above.

I was absent. You wrote:
"All is exactly the same like in the fluids mechanics.

"Exactly" makes it very, very easy to show how an analogy fails:
Describe the laminar flow in terms of
the Reynolds number for
the interface between RF and a Biconical Antenna
and
the interface between RF and a thin wire Antenna."

Maxwell's math is the same as for fluid:

"Maxwell's equations are simply a re-arrangement of relationships worked
out by Faraday in respect of charge and only verified at low speed.
Maxwell discovered that the relationships could be arranged in a form
which mirrored the mathematical description of a fluid"

In fluid are whirls. The magnetic field is like whirl. But not for all
scientists.
"Maxwell's equations" were wrote by Heaviside.
