Defensive Energy Shields

The first and most self-evident application of SET was the creation of force fields for defensive uses. Initially, a force field could only be maintained within a framework designed to hold the energy in the desired shape; but scientists eventually devised fields which did not require a framework.

Types
Force fields, more commonly called energy shields, require large amounts of energy to function, and can be penetrated by certain specially designed projectiles. They come in two variants: the Barrier type and the Dome type. Barriers are simply a straight wall of energy which can serve as a door, a fence, or a temporary cover for soldiers on the field. Domes are created by a central emitter which directs and modulates the energy to a ring of projectors (which are, of course, inside the shield perimeter).

Vehicles
The third, and probably most common, application of energy shields is in the protection of vehicles by means of a series of generators which feed into each other, blanketing the vehicle with energy from as close to the hull as a centimeter to as far out as a third of a meter.
