Microwave Dielectric Characterization of Bulk Ferroelectrics

September 1, 1997
Author(s)
Claude Weil, Richard G. Geyer, L. Sengupta
We discuss the application of existing RF measurement techniques, including waveguide and mode-filtered cavity resonator methods, to the dielectric characterization of bulk high permitivity ferroelectrics at microwave frequencies.

Noise-Temperature Measurement System for the WR-28 Band

August 1, 1997
Author(s)
James P. Randa, L. A. Terrell
The NIST Noise Project has constructed and tested a radiometer for the measurement of noise sources in the WR-28 waveguide band (26.5 GHz to 40 GHz). It is a total-power radiometer which incorporates a six-port reflectometer for the measurement of relevant

Permittivity Characterization from Transmission-Line Measurement

June 1, 1997
Author(s)
Michael D. Janezic, Dylan F. Williams
We analyze three accurate broadband techniques for measuring the complex permittivity of dielectric substrates using coplanar waveguide transmission-line measurements and demonstrate good agreement with single-frequency cavity measurements.

Structure, magnetism, and tunable microwave properties of pulsed laser deposition grown barium ferrite/barium strontium titanate bilayer films

April 2, 1997
Author(s)
Ranko R. Heindl, H. Srikanth, T. Weller, S. Witanachchi, P. Mukherjee, A. S. Tatarenko, G. Srinivasan
Ferrite/ferroelectric films are of interest as they afford dual tunability of the permeability and permittivity using magnetic and electric fields. We have grown bilayered thin films of ferrimagnetic BaFe12O19 (BaM) and ferroelectric Ba0.5Sr0.5TiO3 (BST)
