Electro-Static Shields are a type of force field.
Electro-Static Shield, work by generating static fields, these em fields can stop charge particles, like those typically emitted by energy weapons like blasters, Plasma weapons or lasers. In atmosphere environments, they can stop physical objects by binding the air particles together, stopping sonic weapons.
Despite the variability, they cannot extend beyond a certain distance. Often being used only to block door or hallways.
Thought the design may vary, they are commonly emitted from a dome shaped object(s)
