3-D printers open new design space for wireless devices

Materials scientists and chemists have shown a way to bring electromagnetic metamaterials into the third dimension using commercial 3-D printers. Printed metamaterial cubes were found to interact with radio and microwave electromagnetic waves 14 times more strongly than their 2-D counterparts. The breakthrough could revolutionize the rapid design and prototyping of radio frequency devices for Bluetooth, Wi-Fi, wireless sensing and communications.
