However, the conventional microwave ceramic materials still suffer from limitations such as low permittivity, high dielectric loss, and low thermal stability, which restrict their further development and practical applications. Therefore, it is essential to explore new advanced microwave ceramic materials with high performance and improved properties.Research Objectives:The main goal of this research is to develop high-performance microwave ceramic materials with excellent dielectric properties, high thermal stability, and low dielectric loss. Specifically, the research objectives are as follows:1. To investigate the synthesis and characterization of various metal oxide-based ceramics, such as BaTiO3, MgO, TiO2, and ZrO2, for microwave applications.2. To study the effect of doping and microstructure on the dielectric properties and thermal stability of the prepared ceramics.3. To optimize the sintering conditions and evaluate the microwave properties of the prepared ceramics, including dielectric constant, dielectric loss, and high-frequency conductivity.4. To analyze the mechanisms of microwave absorption and energy conversion in the prepared ceramics, based on the microstructural and physicochemical characterization.Methodology: The research will be conducted through a combination of experimental and theoretical methods. The synthesis and sintering of the ceramics will be carried out using various fabrication methods such ...
