Abstract :
In this paper, an impulse method for the measurement of ceramic-polymeric materials has been presented. Investigations of composite ceramic-polymeric layers comprising modified ceramic ferroelectric powder Ba0.65Sr0.35TiO3 type and a suitable polymer in which the grains of this powder have been discretely distributed, have also been carried out. Obtained results (e.g. tuning ability coefficient of the effective permittivity) show that ceramic-polymer substrates can be utilized in designing new type of antennas and microwave devices.
