"millimeter-wave or mmWave small tablet. size steer signals reaching all corners large room... bring signals from outdoor transmitter indoors thru window... accordion-like array 76 vertical panels reflect and refract radio waves at frequencies above 24 GHz... bandwidth 5 to 10 times greater than maximum capability of 4G... 2 meandering lines thin copper wire flanking 28 broken circles made of thicker wire, constituting meta-atoms... by changing the voltage, we can tune the phase"
