Composites with ferroelectric cubic inclusions are experimentally investigated with coaxial line technique in the microwave frequency range 1–18 GHz. The composites exhibit dispersive effective magnetic and dielectric properties. Strengthening of magnetic resonances with the increase in the inclusions’ number is observed. Electric resonances are damped out significantly due to material losses. The measurement results agree well with theoretical calculations based on Mie theory and Maxwell–Garnett mixing relation. Even number and symmetric arrangement of the inclusions are needed to receive true measurement image in the whole investigated range. Composites utilizing dielectric resonators are attractive in electromagnetic metamaterials fabrication.
