I always though of short haul skip or NVIS as a phenomena rather than a
technology.
Yes, you can intentionally build antennas to favor high angle radiation,
and when you do that you could call it "NVIS Technology."
For most hams operating on 40 and 75/80 meters, antennas with high angle
radiation are more of a default, or accidental situation,
because that is the best we could usually do, due to height limitations
on our horizontal antennas and poor radial systems on our verticals.
Then we work the stations we can work, with the antenna system we have.
And that is often short skip.
Long path DX. Is that a technology or a phenomena? You could call your
stack of six element yagis and your big amplifier "Long Path Technology".
I think that propagation modes including short skip or NVIS are phenomena.
