Abstract :
This paper gives a short introduction into tunable dielectrics for microwave applications based on nematic liquid crystal and Barium-Strontium-Titanate (BST) thin- and thick-films. Due to their tuning voltage dependent electromagnetic properties, both are very promising material candidates for tunable passives in the microwave and millimeter-wave regions. For applications, such as frequency-agile communications and sensor systems we illustrate the challenges of optimization BST films based on a multi-scale view for material, processing, device and application design.
