In this paper, a systematic analysis of native oxides within a Metal-Insulator-Metal (MIM) diode is carried out, with the goal of determining their practicality for incorporation into a nanoscale Rectenna (Rectifying Antenna). The requirement of havi

The combination of high Q dielectric resonators and high temperature superconducting (HTS) films offer many advantages in the area of cellular and satellite communications. The high cost of single crystal dielectrics and HTS thin films may be unattra

A supergain antenna array of closely spaced printed dipoles made of thick film YBCO was designed and experimentally tested. An optimization of the directive gain with respect to interelement spacing, dipole length, and other circuit parameters, subje

Results are presented of the design and performance of a microstrip transmitter/receiver circuit using thick-film yttrium barium copper oxide on a yttria-stabilised zirconia substrate. The resonant circuit is in the form of a ring resonator and the a

Manganites are one of only a small number of material families currently being trialled as room temperature magnetic refrigerants. Here we examine the dependence of the thermal conductivity, K, of La0.67Ca0.33MnO3+/-{\delta} as a function of density,

Transport critical current measurements have been carried out on melt‐processed thick films of YBa2Cu3O7−δ on yttria‐stabilized zirconia in fields of up to 8 T both within grains and across grain boundaries. These measurements yield Jc values

Strip material and substrate losses, that occur at the radiating element and the feeding-matching network of electrically small printed YBa/sub 2/Cu/sub 3/O/sub 7/spl minus/x/ (HTS) antenna systems, can substantially degrade their performance and, th

The magnetic moment of square planar melt processed YBa 2 Cu 3 O 7−δ thick films is observed to scale with the cube of the sample width at 4.2 K, suggesting that current flow on the length scale of the film determines its magnetization at this tem

High-gain arrays are designed from closely spaced printed dipoles, alternately crossed by an integrated series feed. Both the array elements and the feeding and matching network are made of thick film YBa/sub 2/Cu/sub 3/O/sub 7-x/ material for increa
