barrier of solid energy
Force fields are a common technology, used primarily as energy shields for instances where material armor would be inadequate or undesirable. Force fields can also be shaped to create solid objects, such as bridges, walls, and solid holograms.
Force fields can be active or passive
- Active fields are very strong and do not “flicker” in strength or size, enabling much larger fields to be maintained. However, active fields demand massive amounts of energy to maintain. As such, these are typically used by interstellar ships or large installations with a reactor able to provide the necessary energy.
- Passive fields operate in two modes: a low-power “sensing” field, and then a high-power “deflecting” field. When the sensing field picks up an incoming object, the system switches to deflecting mode to stop the object. With advanced control, the shield can go to deflecting mode only when and where there is physical contact with an object. This uses less power than an active field, but has a tendency to “flicker” in size and intensity, and can thus be penetrated by an object that exceeds the system’s reaction time or elastic capability. Passive fields are commonly used for small vehicles or personal defense, as well as solid holograms.
Any two force fields of comparable energy type will blend together on contact, nullifying protective effects between both shielded objects. However, this doubles the field density around both objects and shares the energy load across both power supplies.
Once two force fields are conjoined, all fields must be in perfect frequency synchronization before any other field can meld in.
Dual passive fields are sometimes used to increase overall defensive power and shield size without the energy demands of an active field. If these fields are deliberately desynchronized, they also make it impossible for a force fielded object to “meld through” the defensive barrier.
