     It's just a fancy microwave cavity. The "EM particles" are microwaves. It   
   won't melt, it will arc over internally, causing the magnetron or TWT that   
   generates the microwaves to draw excessive current from its power supply, thus   
   blowing a fuse.   
      
     That's what happens when you try to push RF power into a cavity beyond its   
   design limits.   
      
     Please avoid knocking over known physics while waving hands. (Not that I   
   wasn't doing that in my other posts)
