Abstract
We demonstrate subpicosecond electrical pulse propagation using coplanar air-transmission lines. Rise times of 0.8 ps after 2.8 mm of propagation are achieved with a velocity of propagation which is 86% of the speed of light in vacuum. Our results suggest that intrachip communication in digital circuits with rise times as short as 1 ps is readily achievable using electrical signals.Keywords
