Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
114 words
A TRANSMISSION CIRCUIT FOR VERY HIGH FREQUENCY ELECTROMAGNETIC WAVES, ADAPTED TO THE TRANSMISSION OF A PREFERRED MODE HAVING A CIRCULAR SYMMETRY ABOUT A LONGITUDINAL AXIS OF SAID CIRCUIT , COMPRISED OF A HOMOGENEOUS CYLINDRICAL TUBE MADE OF A HIGH PERMITTIVITY AND A LOW LOSS DIELECTRIC MATERIAL INSIDE WHICH ARE EMBEDDED LENGTHS OF THIN METALLIC WIRES SPACED AND INSULATED FROM EACH OTHER AND SUBSTANTIALLY ORIENTED IN A DIRECTION IN WHICH THE ELECTRIC FIELD OF SAID PREFERRED MODE HAS ZERO COMPONENT, IN WHICH SAID PREFERRED MODE IS A FUNDAMENTAL CIRCULAR-SYMMETRICAL TM MODE AND IN WHICH SAID WIRE LENGTHS ARE ORIENTED IN PLANES SUBSTANTIALLY PERPENDICULAR TO SAID AXIS AND ALONG CIRCLES HAVING THEIR CENTER ON SAID AXIS.
Claim 2
Dependent Claim
