First Claim
Patent Images
1. A transmission line apparatus comprising:
- a wedge-shaped shield of dielectric material having an internal angle and an external apex formed by the intersection of the two sides thereof;
means positioned within said internal angle for the propagation of surface waves; and
means for maintaining said surface wave propagation means within said internal angle and in contact with each side of said wedge-shaped shield.

Abstract
A continuous, self-supporting microwave transmission line along which ultra short pulses of microwave signals may propagate over distances of several hundred feet with minimum pulse distortion and signal attenuation. Propagation along the line is accomplished by an electromagnetic field thereabout that is sensitive to objects positioned in the proximity of the transmission line, a characteristic that may be utilized in short pulse reflectometer systems for monitoring and control of vehicles on a prescribed course.

7. A surface coupling apparatus comprising:
-
a first transmission line which comprises; a wedge-shaped shield of dielectric material having an internal angle and an external apex formed by the intersection of the two sides thereof; means positioned within said internal angle for the propagation of surface waves; and means for maintaining said surface wave propagation means within said internal angle and in contact with each side of said wedge-shaped shield; and a second transmission line positioned to be in an energy coupling relationship with said first transmission line, said second transmission line comprising; a wedge-shaped shield of dielectric material having an internal angle and an external apex formed by the intersection of the two sides thereof; means positioned within said internal angle for the propagation of surface waves; and means for maintaining said surface wave propagation means within said internal angle and in contact with each side of said wedge-shaped shield. - View Dependent Claims (8, 9, 10)
