Abstract

This work outlines the material processing technique used to fabricate a multilayer ferroelectric material BST (barium strontium titanate). The composition and thickness of each layer can be controlled such that a tunable multilayer frequency-selective device can be fabricated. The BST materials can be processed by a combination of sol-gel powder processing, tape-casting and microwave processing to yield a multilayer composite material having variable and tunable dielectric properties. For thinner layers, microwave assisted plasma deposition is used to prepare thin film BST from a sol-gel slurry.
