Abstract
Dielectric ceramics such as BaTi4O9 have been widely used as microwave resonators in communication systems. In order to study the effect of doping on dielectric properties, infrared reflection spectra of BaTi4O9 doped with Mn, Sn, Zr, Ca, Sr, and Pb were studied from 20 to 6000 cm-1 at temperatures ranging from 15 to 297 K. The reflectance data was converted to the dielectric data using Kramers-Kronig analysis. The dielectric parameters k, Q, and τk calculated from the reflectance data were in agreement with resonant cavity measurements at 4 GHz.
