The primary component of shield technology is a powerful electro-magnetic field. This field in itself can be used to disrupt physical objects or charged objects. However, its real function is to hold a web of cold plasma in place. The ionised plasma deflects surface electrons of incoming atoms.
This type of field is extremely effective at dispersing lasers, particle beams and projectile weapons. Plasma beams pose an issue as it heats the cold plasma causing a ship to bake within its own field. To prevent the shield from overheating a shield AI will shut down cells of the web to preserve its neighbours allowing a focussed beam through to the hull.
To counteract plasma beams a further development, which enhances all the protective aspects of a shield, is the incorporation of an AEG. With an AEG there isnít enough time to for a plasma beam to overheat a cell before itís deflected to another by the gravity field.
Shields are generally overcome by sheer weight of fire. Systems become overstretched and weapon affects become cumulative. Shields also suffer from plasma loss, even more so under fire. Eventually the large amount of resources required to keep shielding in place becomes too much to sustain and the shield fades.
Shield resources can be preserved by powering sections on and off when needed. For instance when running away, why shield the forward areas? In reality these resources rather than saved are directed to the area under fire strengthening shielding in the area under attack. The obvious counter to this tactic is to hit a ship at an unexpected angle when already under fire from other quarters.
Once a ship is down to its armour its lifespan is measured in minutes but even then solid armour may give a crew enough time to turn the tide or escape. Gravity, magnetic and reflective effects have always been applied to armour plate to mitigate the differing type of incoming fire.
Point Defence Systems.
Point defence systems are made up of clusters of small calibre weapons that are able to track fast moving incoming munitions such as torpedoes. Originally these armament clusters attempted to destroy incoming projectiles before they cause damage to a ships hull. Their fire could not penetrate a ships shielding and hence their defensive capability was usually a last ditch attempt. This limitation was overcome partially by disabling shields until the last second but this endeavour was far too risky. The final solution was to create the point defence drone. These drones are small craft that operate beyond the shield allowing them to preserve the shield as well as the hull. The increased mobility of point defence systems also allows them to be concentrated in areas under heavy attack.
