The Radar lore has it that a Sailor walked somewhere in front of the new Radar antenna and the chocolate bar melted. And yes, you would pick the usual 2.4 GHz since water molecules have a resonance there that the builds up heat due to friction so said the physics prof. And we have hacked microwave ovens to get a cheap source of high frequency high power, just remove the door and bypass the interlock. You sure don't linger when moving devices in or out of the active field. We stood to the side and reached over, quickly.

To: "Bill Owsley" <[email protected]> Cc: "IEEE EMC forum" <[email protected]> Date: Friday, February 4, 2011, 5:47 PM I think this 'phenomena' was discussed within the past couple of years. 1) Are you asking how much cell phone power it takes to cook popcorn? I don't know, but I bet the cell phone wouldn't meet the SAR limit. And they used differnt model cell phones, too. 2) Are you asking how much power a microwave horn concealed under the table would have to emit? I don't know that either, but the popcorn was put on the table for about 30 seconds before it popped. (Ignore the ritual of making the cell phones ring.) More interesting questions are: - Is it feasible to hack a microwave oven apart to get a powerful signal source for this demonstration? - If you could pick a signal frequency for the test, would you pick the usual 2.4GHz band used for microwave ovens, or something different? I remember hearing anecdotes about engineers (or was it Navy personnel?) cooking hot dogs in front of microwave antennas for fun. Pat Lawler EMC Engineer SL Power Electronics Corp.
