Investigations of tunability of ferroelectric ceramic-polymer composites

摘要

In this paper results of investigations of ferroelectric ceramic-polymer composites for tunable sub-THz devices are presented. Influence of a polymeric binder and type of ferroelectric powder on tunability is studied. Setup for tunability measurements is also described. Measurement results are shown and compared. Obtained results are very promising and suggest that developed composite materials can be an alternative to currently used state-of-the-art tunable materials operated at sub-THz frequency band.
