Microwave weaponry sounds cool because microwaves react violently with metals (put a piece of metal in a microwave oven and see why (don't actually do that, it's very dangerous, but you probably already knew that)), effectively destroying a ships hull.
Microwaves DO NOT harm metals at all. They bounce back on colliding with them. When you put a piece of metal in a microwave oven, the angle it makes with the base of the microwave determines the nature, intensity of sparks generated which are the REAL danger. (Sparks actually just increase the inside temperature insanely fast.)
Verification? Check the inner walls of your microwave oven. THEY ARE MADE OF METAL.
Also tell me if I have given some wrong information. I have a habit of sleeping in Science classes.

Also, I don't believe anyone has made a Ballistic Missile Saturation Device, involves the use of multiple fusion warheads to saturate a field of effect.
You mean something like Slammers in BP or Piranhas in Freespace 2, right?
Also any thoughts on dark matter weapons? Like for example they can pierce right through the shield because they do not follow the orignal properties of matter or undetectable weapons for stealth fighters since dark matter cannot be detected easily?
