Electrodynamic properties of solid solutions 0.98(xPbTiO₃–yPbZrO₃–zPbNb_2/3Mg_1/3O₃)–0.02PbGeO₃ in the microwave range

Abstract

The behavior of samples of four-component solid solutions (SS) 0.98(xPbTiO₃–yPbZrO₃–zPbNb_2/3Mg_1/3O₃)–0.02PbGeO₃ in an electromagnetic field of the microwave range has been studied by the microstrip method. Dependences of frequency dispersion of the transmission coefficient, the reflection coefficient, and the degree of absorption of the material on PbTiO₃ concentration have been analyzed. It has been found that the flat disk samples with the highest PbTiO₃ concentration in the segment of the regular microstrip line have the widest absorption band (10 MHz ÷ 2.5 GHz).
