I have had a hard time myself figuring out what kind of weapon it was that Cay Van Ash had Fu Manchu using in his book, but gleaning together all the tidbits he gave came up with one conclusion that fits all the facts given. I'm not sure if it would spoil the story in any way if I told you what it is straight up - I mean, it's not like any of the heroes has the scientific training to deduce the physics behind the device, nor would it make any difference to the story if they did. Your call, should I tell you?
No - don't tell us. Not becuase it would spoil the story but someone is bound to nitpick on the science.
You've described the device and its limitations and its effect.
HOW it does all these things is irrelevant to the story.
