Field Amplifier

A field amplifier is a device which creates a localized increase in the density of the ue field, amplifying the effect of magical devices within it.

Design

A field amplifier has three parts:

To use a field amplifier, a magical device, called a "sink", is placed inside the cage. When magical energy is supplied to the field modulator, it energizes the warp lattice. The warp lattice draws in the ue field, creating a region of high ue density inside the cage and reduced ue density in the area around the cage. If the polarity of the ue field in the cage aligns with the magical field in the sink, the sink's magic has a more pronounced effect and increases in strength.

Performance

Field amplifiers are judged on two main metrics: amplification magnitude and magnification factor. Amplification magnitude, or simply "magnitude", is the ratio between the average ue field density within the wave lattice and density at ambient conditions. Magnification factor is the ratio of the increase in magical energy output from sink to the magical energy supplied to the amplifier.

Lattice saturation

Because the warp lattice stretches the ue field in the surrounding area, it reduces its own efficacy as the field surrounding the cage thins, lowering its magnification factor. As more energy is supplied to the amplifier, the magnification factor decreases further. At a certain level, the ue field around the cage becomes so thin that further energy no longer produces a significant increase in magnitude. Saturation can be mitigated by shaping the energy vacuum such that the warp boundary is as close to the warp lattice as possible, reducing the effect.

The lattice saturation coefficient is a measure of efficiency loss due to lattice saturation. It can be calculated with the equation

where

Alignment coefficient

The alignment coefficient is a value representing the alignment of the sink's magical field with the ue field inside the field amplifier. This can be found by taking the dot product of their polarity vectors.

Energy vacuum

When the field amplifier is running, it creates a disturbance in the ue field called an energy vacuum. The energy vacuum is divided up into several regions:

Maximal point

The area of maximum ue density. As most cages are cylindrical, this area is typically shaped a line running along the center of the warp zone. In large amplifiers when a low energy is supplied, the warp lattice will fail to push the ue field to the center of the cage and the maximal point will fall somewhere along the radius of the warp zone.

Warp zone

The region inside the cage where ue density is above normal. Density peaks at the maximal point and trails off as you get further away.

Warp boundary

The edge of the warp zone. Ue field density is equal to ambient. The warp boundary is always within the warp lattice, but the exact distance depends on the design of the warp lattice. Most designs try to get the warp boundary as close to the warp lattice to reduce lattice saturation.

Minimal point

The area of minimum ue density.

Energy basin

The region outside the warp zone where ue field density is below normal. Density continues to fall as you travel further from the warp boundary until you reach the minimal point. Past there, the warp lattice's field begins to trail off and density begins to rebound, eventually returning to ambient levels.
