Here goes:

First off, 'battle shields' are NOT ramped-up deflectors; the deflector dish puts out 'low-power' paired tractor/repulsor beams to form a 'wedge' that pushes aside everything from particles to meteors. (In my opinion.)

Shields, on the other hand, are 'simply' an energy-conversion matrix; just as photovoltaic 'solar panels' convert sunlight into electricity, so do shields convert various forms of power (including kinetic, or 'impact',) into some form of storable power. However, like solar panels, there is an efficiency gap - it only converts a percentage, and the 'left over' is what gets through to the ship.

I would presume later-generation sheilding would have a higher conversion efficiency that older types...

(All the above is a combination of seeing shields in action, extrapolation from 'technobabble', and an awful lot of pure guesswork. Take it as you will..)
But in TOS (seems to have ben rectified in later shows) Kirk, when going into battle would call for deflector screen up soemtimes, and sheilds other times.

While I love your idea, and is probably very true for TNG-onwards ships, it seems by those things that maybe in the 23rd century they both shared the same emmitters, or were just "Ramped up deflectors?"

As far as I know shields are a distortion field, which distort the space around the ship and therefore make it impossible for weapons to reach the ship.

So it's not an energy barrier?

...hmm, sounds almost like a merging of the warp-field and the shields.

Doesn't seem likely, though....

I would agree.

Don't know if you've ever had a chance to read the 'Honor Harrington' series by David Weber. (Really good books; some truly epic space battles...)

In the series, ships are driven by 'impellers' that created stressed gravity bands that 'pull' the ship through space. When these are running, the portions of the ship covered by the impeller bands are nigh-well impervious to damage - no known weapon, not even 'grasers' (gamma-radiation lasers) can get through the band... not surprising, as it's a >450G gradient.

You hit ANYTHING with a sudden four-hundred-plus gravities, and you'll fold, spindle and mutilate it but good! (*Grin*)

I just thought THAT was an interesting implementation of 'sheilds'; being a logical yet unexpected 'spin off' to the drive technology itself.

No haven't read the novels, now I'll have to find them...lol.

Now I can buy that technology, gravity seems to be a constant as we peek more and more into the universe.

It's an energy forcefield by any other name.

Basically, a forcefield is a spatial distortion, but of a non-propulsive nature, IMO. While I'm fairly sure there's some sort of subspace activity at work, shields probably generate more of a graviton-based energy field...

Not necessarily; there are many theories for shield technology - i.e., energy disruption/ deflection/ absorption/ conversion, etc.

Some ARE based on distorting local space and/or time... but in the Star Trek universe, it seems to me that the concept of absorption/conversion more closely fits observed phenomena.

(Of course, as I have mentioned before, due to how little 'cause' is discussed in-show, anything based on observed 'effect' is most highly theoretical.)

So, I'm certainly not saying anyone else's theories are wrong; I would just like to see, (as I have provided for my theorem), how one would justify/explain any other assertion.

By all means, should anybody out there have an 'Exhibit 'A'' they wish to enter into evidence, please feel free to do so. While I feel my theory is fairly sound based on the evidence as I currently understand it, I am more than willing to entertain any new datum/theory/counter-proposal...

'Worst case scenario'...? Well, here's my fundamental outlook, vis-a-vis 'free speech':

"I may not agree with a single thing you have to say; nevertheless, I will defend - to the death, if necessary - your right to say it."

I really am talking solely about the Star Trek Universe, in which that is the basic description of a forcefield and the basic principle behind a deflector--or at least as the TNG Tech Manual puts it.

It describes shields as a graviton-based distortion field that aborbs and dissipates the energy from a hit in the form of heat, visibly seen as a brief flash upon impact. The spatial distortion is confined solely at the point of impact, causing an object to bounce off or stop just shy of reaching the actual hull of the ship. The strength of a shield is based on its ability to effectively dissipate heat/energy. When the shield generators have exceeded their maximum rated dissipation capacity, the ability to protect the ship begins to drop by percentages the longer the shield is under attack.
