   It's happen to all of us, around you cellphone, your boss are saying something important, and then the connection instruction to drop out. Now a team of physicist 1 at Demag lead by A U P, has demonstrated that a new kind of radio tuner that is far more sensitive to defense 2 signals. The technique could eventually mean fewer dropped calls, better GPS coverage 3, faster WIFI, and much more detailed 4 images from a marine 5 scanners. the tuner includes a novel component 6: a tiny reflective membrane 7, just half a millimeter on the side and only a hundred nanometer seek. It functions in the xx as a capacitor, and when radio waves pass through the container, the minuscule 8 volt 9 shapes make the membrane bounds like a choppering. Laser light reflecting of the membrane and interfering 10 of itself turns the nanometer high waves into strong clear signal. The report is published on Sign Arch. The scientist are signed by how the technology might trap in the pictures by radio telescopes. But wouldn't that also be nice to actually get decent phone reception inside the parking dash
