yeah, ionization is literally defined as adding or taking electrons from something. so although microwaves don't ionize water, they ionize metals, if the metallic particles have some level of conductivity between them and form a body of sufficient size to tune to the radiation, acting as a receiver, and the electrons are then absorbed into surrounding tissue, and other things like oxygen or heavy metal particles, reducing them and making them active. i personally don't see the value in most applications of microwave radios. i saw a great saying on an antique phone in Funchal that said that when phones were tied to the walls we were more free. i prefer desktop computers and when i walk out of the house i'm offline. offline time has become so scarce people don't realise how valuable it is. you can think.
