ABSTRACT:
A structure for guiding millimeter wave radiation employs a resonant coplanar transmission line on a transparent substrate. A very short, picosecond, pulse is generated on the transmission line. By having the upper half plane air, the pulse will radiate into the substrate and be guided as millimeter wave from a distributed source and formed as a point source of radiation.
