Project description
Expanding the landscape of microwave communication systems
Microwave communication systems face a critical challenge in the search for materials with tailored dielectric properties at millimetre-wave frequencies. The literature underscores the significance of low-loss dielectric ceramics with thermal stability and low permittivity. However, existing materials require improvements through new production techniques or compositions. With the support of the Marie Skłodowska-Curie Actions programme, the HECPC project will address this gap by introducing novel approaches in the preparation and characterisation of diopside CaMgSi2O6-based ceramics. Specifically, the research will strategically introduce adjustable dielectric properties and low-temperature processing by cation substitution via high entropy strategy and a new ultra-low sintering method called cold sintering, respectively.
Objective
The search for microwave materials with tailored dielectric properties in millimeter-wave frequencies has been the objective of a significant number of manuscripts reported in the literature. Dielectric ceramics with low-loss dielectric, thermally stable and low permittivity have received extensive attention owing to their significant application prospects in microwave communication systems. It is therefore desirable to introduced new production techniques, new compositions or improves the properties. The proposed research will intellectually contribute to the scientific literature through the preparation and characterization of new dielectric materials belonging to the diopside CaMgSi2O6 based ceramics. This proposal seeks to achieve the following specific objectives: (1) Consideration of the impact of different types and concentrations of dopant such as Sr and Ba for large divalent cation (Ca) and Zn, Co, Mn and Ni for small divalent cation (Mg) via high entropy strategy on the structural, microstructural and microwave dielectric characteristics of CaMgSi2O6 based ceramics. (2) Evaluation of the effect of thermal annealing time and temperature on the final performance of high entropy CaMgSi2O6 based ceramics. (3) To explore the relationship between high entropy design and microwave dielectric properties. (4) Fabrication of CaMgSi2O6 Polyethylene (PE) composites using cold sintering process and investigation of the pressure, temperature and transient solvent type on densification, microstructure and microwave dielectric properties. State of the art and new experimental techniques and methods will be used in order to achieve the goals of this proposal.
