Abstract
A metal-foam structure is used to shield or reduce harmful electromagnetic waves that are generated by electronic devices. A metal-foam material has regulated pores and is incorporated in an electronic device. The metal foam structure shields, prevents, or reduces harmful electromagnetic waves generated by the electronic device from reaching the human body or interfering with a sensitive electronic component. This metal foam is a relatively lightweight material having regulated microscale pore structure. The pores in the metal foam can also form directionality relative to the direction of incoming electromagnetic waves for more effective reflection or absorption of electromagnetic waves. The metal foam can also be used as both an electromagnetic-shielding and a heat-dissipating component for electronics including popular consumer electronics such as mobile phones, notebooks, and high-power desktop computers.
