Maybe shields have some kind of magnetic field (we already know they have subspace field) beneath the shield, which is specifically used to weaken (disperse) bleedthrought that passes throught primary shield "membrane".

Possibly. Out of curiosity, what does the subspace field do?

EDIT: Might it be the subspace field? We know that DS9 was able to move at high speeds without having to worry with debris or anything shearing them apart. That might suggest some sort of protection created.

Gravitons are subspace distortions, which literally bend space, so the subspace field is the deflector-shield that causes attacks to bend away from the ship, as if the ship was moved out of the way-- which is literally is, "relatively" speaking.

DS9 was able to move fast in "The Emissary" because Chief O'Brien modified the station's normal subspace deflector-shields to act as a warp-field, which is based on the same graviton-based space-bending principle. Normally, the station's maneuvering-thrusters would have taken six weeks to get to the wormhole, but they got there in a matter of hours with this modified warp-field.

However when a ship is moving at warp, it isn't really moving faster than lightspeed, but is actually moving closer to 0.1C-- which is still pretty fast. So in the case of DS9, there wasn't much to worry about; O'Brien simply cranked up the deflectors to full power possible for the duration of the flight.

Graviton is theoretical particle responsible for gravitation. If it creates subspace distortion, I don't know.

http://en.wikipedia.org/wiki/Graviton

And when ship is moving at warp, it is actually stationary. Rather, it creates it's own spacetime bubble (tearing out already existing spacetime for use would result in creation of either black holes or wormholes), and then bubble moves around, carried by gravimetric/subspace/timespace distortions in front and back of the ship.

Subspace field protects from subspace component of weapons such as phasers, if there is subspace component. But it definetly blocks sensors - in Wounded, we know that high-powered subspace field can block sensors, and shields also block sensors.

I do. Gravity, by definition, is a subspace distortion.

That's not stationary, since it has to move through space to get where its going; it can't just pass unimpeded as if intervening space isn't there: that would be a wormhole, and the ship can't create those. Rather, warp-drive can accelerate the ship relative to normal space by converting matter and anti-matter to kinetic energy, and the warp-field amplifies the ship's motion via reverse-Lorentzian shift of dilating space and compressing time.
True, it only does so for the space occupied by the ship, but it still moves.

A cloaking device is also a modified deflector. In contrast, SW-cloaking devices must be EM-based and therefore far less efficient, that's why a huge ship is needed in order to power one without their magic New Age crystals. :D
