The electromagnetic property evaluation focuses on modeling composite structures in COMSOL Multiphysics to determine their effective permittivity, permeability, and conductivity across 2–10 GHz frequencies. we use field averaging and retrieval methods to extract the intrinsic parameters from volumetric simulations, ensuring results are accurate by comparing with analytical models and published benchmarks. This process supports the design of materials tailored for radar absorption and electromagnetic performance, advancing stealth technology in aerospace applications. 

The work focuses on electromagnetic wave interaction and radar cross section (RCS) evaluation of composite materials using COMSOL Multiphysics. Through broadband simulations (2–10 GHz), we analyze the propagation and absorption of electromagnetic waves in layered composites, utilizing field distribution and energy dissipation methods. RCS calculations are performed to assess and optimize the stealth performance, enabling material designs that significantly reduce backscattered signals. This integrated approach to wave-material interaction and RCS optimization advances the development of high-performance radar absorbing composites for aerospace applications. 

Apart from my research in electromagnetic materials and stealth technology, I am deeply passionate about aeromodelling, focusing on UAV design, fabrication, and testing. I have hands-on experience developing unmanned aerial vehicles for applications such as surveillance, payload delivery, and specialized missions including suicide drone operations. My work integrates innovative design concepts and practical engineering, ensuring robust performance and adaptability across diverse aerospace scenarios. This passion not only strengthens my technical expertise but also drives my commitment to advancing real-world UAV technology for strategic and humanitarian purposes.
