Aluminum foil helmet of yours isn’t doing so much after all, you’re probably on the look out for some new tech to save your noggin.
The new “left-handed material” made by Tongji’s physics department is a metal structure that can reverse the spread of natural electronic-magnetic waves — away from the human body — and therefore control the wave direction.
 Cell phone radiation can be reduced with this new material developed by Tongji University for use in manufacturing antennas. The material is also able to locate nearby telecommunication transmitting stations according to wave-length differences and send out electronic-magnetic waves particular to that direction.
“The finding has an important practical use in helping redirect radiation from cell phone electronic-magnetic wave transmission once the material is applied in cell phone antenna production,” said Li Hongqiang, chief researcher of the program.
All cell phones currently in the market adopted ordinary antenna, which send out electro-magnetic waves to all directions, including transmission stations and human bodies. Radiation created by frequent cell phone usage may trigger headaches, poor memory and even deafness, researchers said.
The researchers have applied for a patent and have been honored by the Shanghai Science and Technology Commission.
