"continuous 'wide-angle' beam steering... track moving mobile phone user in same way satellite dish turns... significantly enhanced speeds... fully compatible with existing 5G specifications... simple to fabricate... size of iPhone, the uses metamaterial made from a metal sheet... array regularly spaced holes micrometers in diameter... actuator controls height of cavity... antenna control radio wave—effectively 'concentrating' beam into directive signal, and then redirecting this energy as desired"
