Microwave Transmission Line and Method of Modulating the Phase of a Signal Passed through Said Line.
Patent Application, Filed 5 Feb 90,
DEPARTMENT OF THE AIR FORCE WASHINGTON DC
Pagination or Media Count:
A microwave transmission line is provided including a class of dielectric materials known as relaxor dielectrics having very dielectric constants of greater than 1000, low dielectric loss and large variations of the real part of the dielectric constant with varying temperature. The phase of a microwave signal passed through such a transmission line is modulated by subjecting the transmission line to light that is absorbed in the dielectric layer causing a variation in the dielectric constant and a change in the velocity of the continuous microwave signal passing through the transmission line.
