Abstract :
In a brief introduction the ferroelectric varactors are compared with the other tuneable technologies and identified as one of the most adequate components for utilizing tuneable metamaterials. The main features distinguishing the ferroelectric varactors are the extremely low control power consumption and high speed. Some examples of the ferroelectrically controlled ID metamaterials are given followed by an example of a microstrip line based on a tuneable ground plane in the form of 2D metamaterial.
