Boeing, the world’s largest aerospace company and maker of fine passenger planes and unmanned drones, recently patented a concept for what some are hailing as a “Star Wars-like force field.” The patent, titled “Method and system for shockwave attenuation via electromagnetic arc,” has inspired a number of Star Wars and Star Trek references, as well as the requisite arguing over which franchise actually inspired the patent.
So, how does this “force field” really work?
However, some writers and commenters have already pointed out the limitations of using sci-fi metaphors for describing military technology, arguing that the “force field” as conceived in the patent is not really a visible, impermeable membrane like the ones found in the final battle of “The Phantom Menace.” So how exactly would this “force field” work?
The immediate aftermath of an explosion – say, one targeting an occupying imperial military force – entails several immediate dangers for its targets, among them flying shrapnel and shockwaves. Protective armor and vehicle plating can protect military personnel and vehicles from shrapnel to a certain degree, but the astounding kinetic energy transferred to the human body via detonation waves can be as fatal as an encounter with a vehicle moving at high speed.
According to the patent, Boeing’s device will attempt to solve the problem of shockwaves by “heating a selected region” of the air through which the shockwaves are traveling to “create a second, transient medium that intercepts the shockwave and attenuates its energy density before it reaches a protected asset.”
The patent outlines several potential “embodiments” of the technology, one of which involves detectors that trace the source of the explosion and the path of the shockwaves. The detectors would then communicate with an arc generator, which could generate a plasma field with lasers or microwaves that would significantly reduce the energy impact of the shockwaves.
