"Captain, magnetic seals in the anti-matter chamber are decaying!" "Shields up!" Now that we have that out of our systems, let's start by saying that unlike a Star Trek-style deflector, Boeing's plasma "shield" could never block shells or bullets, let alone anti-matter explosions. But if its patent "for shockwave attenuation via electromagnetic arc" ever amounts to anything, it'd still be a technological tour de force. The idea is to harness electrical energy to stop or slow down the shockwaves created by explosions, which can do just as much damage as shrapnel.
