For my industrial design project, I am redesigning the microwave oven and adding some extra functions. Is it possible for microwaves to somehow measure food properties such as calories, sugar, salt, vitamins, and fat content? How can I translate those readings onto an LCD display so that the user can see them, and can they also be transferred to a computer via Blue tooth? What you propose to do is far more difficult than you imagine. Determining the chemical contents of food is hard, even with a well-equipped laboratory and permission to destroy the food in order to study it. The idea of analyzing a casserole in detail simply by beaming microwaves at it is science fiction. Think how much easier airport security would be if they could chemically analyze everything that came in the front door just by beaming microwaves at it.
