Resonant Microwave Response in Strontium Titanate Single Crystals

Materials, based on strontium titanate, have many applications in microwave technology. The main methods for achieving target characteristics when developing such materials are modification of the composition and creation of low-dimensional structures. Due to the high cost of single crystals of suitable shape for measuring electrical parameters using standard methods, ceramics and composites are being considered as an alternative. The work proposes to use a set of simpler measurement techniques that allow for a primary analysis of the microwave response of single-crystal materials and simplify further modeling and calculations. The results of calculating the resonance response of a model single-crystal sample of strontium titanate are presented. The influence of the features of measurement techniques on the final results is analyzed. Conclusions are drawn about the feasibility of conducting comprehensive studies using various techniques. The results obtained will help in further calculations and modeling of the electrical parameters of single-crystal samples of functional materials.
