Dielectric properties of doped titanates of transition metals in the millimeter-wavelength range

Resumo

Dielectric properties of ceramic titanates of nickel, cobalt, and manganese and their isomorphically substituted solid solutions are studied. Iron and magnesium are used as dopants. Original methods for solid-state synthesis of titanates allow variations in the dispersity of products. The structure and phase composition of products are analyzed. Microwave measurements of permittivity are performed in a frequency interval of 12–38 GHz. Real and imaginary parts of the permittivities of titanates are determined.
