Tarun Katheriya is a physicist with extensive expertise in the synthesis, characterization, and analysis of advanced functional materials, particularly negative-permittivity ceramics, perovskites, and multifunctional composites for electromagnetic interference (EMI) shielding and wearable electronics. His Ph.D. research focused on developing epsilon-negative materials, including layered perovskites and glass-ceramics, with tunable dielectric and conductive properties. He has synthesized a variety of electro-ceramics and glass-ceramics, exploring their dielectric behavior through classical and modified Drude models, and demonstrated their EMI shielding effectiveness. Notably, his work includes investigating coil-less inductive properties in conducting ceramics and studying the electrochemical performance of these materials. Katheriya has contributed to understanding the correlation between conductivity and permittivity in doped perovskites, as well as high-temperature dielectric properties in layered oxides. His research integrates experimental synthesis with theoretical modeling, advanced characterization techniques such as XRD, SEM, impedance analysis, and vector network analysis, and simulation tools including FullProf, Zview, and Gaussian. His published work highlights innovations in metal-free nanocomposites, negative-permittivity behavior, and multifunctional EMI shielding, positioning him at the forefront of materials development for next-generation electronic applications.
