Electrically Controlled HTSC/Ferroelectric Coplanar Waveguide
Artikel i vetenskaplig tidskrift, 1994

It is shown that in an integrated YBa2Cu3O7SrTiO3 structure coplanar waveguide (CPW) electrical control of microwave propagation characteristics is possible. Microwave losses of less than 0.2 dB/cm at 10 GHz can be achieved at liquid nitrogen temperatures, provided ferroelectric films with perfect crystalline structures are used. Electrically controlled changes in effective dielectric permittivity of more than 40% are predicted at 77 K and 10 GHz. Sections of these CPWs can be used in electrically controlled phase shifters and resonators.
