Increasing data traffic and bandwidth-hungry applications require electro-optic modulators
with ultra-wide modulation bandwidth for cost-efficient optical networks. Thus far, integrated …

Dielectric resonators are key elements in many applications in micro to millimeter wave
circuits, including ultra-narrow band filters and frequency-determining components for …

The dielectric anisotropy of Al 2 O 3 is studied here by characterizing W-band (75–110 GHz)
complex permittivity of four different orientations of sapphire (Al 2 O 3 single crystals). This …

Epitaxial Tl/sub 2/Ba/sub 2/CaCu/sub 2/O/sub y/and Tl (Ba, Sr)/sub 2/Ca/sub 2/Cu/sub
3/O/sub y/thin films have been prepared on CeO/sub 2/buffered sapphire substrate by an ex …

We investigated the effect of introducing artificial pinning centers (APCs) into YBa 2 Cu 3 O 7-
δ (YBCO) thin films to reduce the microwave surface resistance (R s) in a high dc magnetic …

We investigated the dc magnetic field and temperature dependences of the microwave
intrinsic surface resistance (R s int) of YBa 2 Cu 3 O y (YBCO) superconducting thin films …

Tl2Ba2CaCu2Oy (Tl-2212) and Tl (Ba, Sr) 2Ca2Cu3Oy (Tl-1223) superconductor thin films
have been prepared on CeO2 buffered sapphire substrate by an ex situ process namely …

We investigated the effect of artificial pinning centers (APCs) in YBa 2 Cu 3 Oy (YBCO) thin
films to reduce the surface resistance (Re). The introduction of APCs can increase the critical …

We investigated the behavior of the surface resistance (R/sub s/) of high-temperature
superconductor (HTS) thin films exposed to a dc magnetic field (parallel to the c-axis) …

We investigated the dc magnetic field and temperature dependences of microwave surface
resistance (R s) of high-temperature superconductor (HTS) films. Previously, we reported …
