   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 physicist1 at Demag lead by A U P, has demonstrated that a new kind of radio tuner that is far more sensitive to defense2 signals. The technique could eventually mean fewer dropped calls, better GPS coverage3, faster WIFI, and much more detailed4 images from a marine5 scanners. the tuner includes a novel component6: a tiny reflective membrane7, 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 minuscule8 volt9 shapes make the membrane bounds like a choppering. Laser light reflecting of the membrane and interfering10 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
