Announcements are often heard on airplanes requesting that passengers refrain from using portable electronic devices in the cabin. This is because there is the possibility of radio waves from portable electronic devices (PEDs) carried aboard interfering with aircraft navigation systems (a phenomenon known as electromagnetic interference, EMI). There has therefore been strong demand recently for the development of EMI proof aircraft.

    We are now studying radio wave propagation from PEDs in the cabin to the aircraft system directly or via antennas. We are also working to make EMI proof aircraft.

    We believe that this research will help create standards to allow the use of PEDs without jeopardizing flight safety.
