We discuss the results of a study on growth by laser ablation of YBa2CuO7 thin films on polycrystalline and annealed vicinal (001) MgO substrates. In both instances the films were found to grow predominantly with c axis normal to the plane of the substrate
We discuss the results of a study of the effect of a substrate preparation on the microstructure and superconductive properties of YBa2Cu3O7 think films formed by laser ablation on (001) MgO substrates. Thermal annealing of the substrates is found to be
This paper investigates a general method of characterizing microwave test fixtures for the purpose of determining the S parameters of devices embedded in the fixture. The accuracy of the technique was studied and compared with that of the common open-short
When an electrical circuit is enclosed in a metal package large enough to support resonant modes within the frequencies of operation of the enclosed circuit, coupling between the circuit and these resonant cavity modes may disturb circuit operation. These
Two methods are used to de-embed coplanar probes using offset coplanar waveguide shorts and transmission lines. The accuracy of the de-embedded measurements is verified. The S parameters of lumped standards provided by the manufacturer of the probes are
A transition between a coplanar probe and a microstrip transmission line is reported. The transition is significant in that it does not require substrate via holes. A set of microstrip impedance standards were developed for the purpose of de-embedding the
