As for testing, start out as the diagram shows. But I have no ideas on how to replicate the end results of the myth.
i.e. A cooked egg
Uh, toss it in a microwave oven? After all, cell phones and microwave ovens work in approximately the same frequency range (I don't remember the exact frequency of a microwave oven but it is close to 2.4GHz). On a related note, at one time there as was a genuine scare that as computer processors increased in speed they would require microwave oven-like shielding to protect the user. Today's processors are well past that point and as far as I know no one has experienced cooked brain cells unless you attribute forum addiction as a form of brain damage.
