Advanced Electromechanical Simulation Framework for Hybrid Composite Radome and MEMS Systems Using Multi-Physics Modeling Techniques

Abstract

The escalating demand for high-performance aerospace systems and microelectromechanical systems (MEMS) has necessitated the development of advanced simulation frameworks capable of accurately capturing complex multi-physics interactions. In response to this challenge, the present study proposes a robust and comprehensive electromechanical simulation framework that synergistically integrates Finite Element Method (FEM), Finite-Difference Time-Domain (FDTD), and Multi-Resolution Time-Domain (MRTD) techniques for the in-depth analysis of hybrid composite radomes and MEMS-based structures.

The proposed framework incorporates multi-domain modeling, nonlinear dynamic analysis, and uncertainty quantification to enable high-fidelity prediction of system behavior under diverse operational conditions. Hybrid composite materials, including E-glass and aramid fiber-reinforced epoxy with foam-core sandwich configurations, are systematically investigated for their electromagnetic transparency, dielectric efficiency, and structural resilience.

Simulation outcomes reveal that the optimized material configurations significantly enhance electromagnetic transmission efficiency, minimize signal attenuation, and improve mechanical stability. The integration of machine learning-driven surrogate modeling further accelerates computational performance while maintaining high predictive accuracy, thereby enabling efficient design space exploration and optimization.

Comparative and statistical analyses substantiate the superiority of the proposed framework over conventional single-domain approaches in terms of accuracy, computational efficiency, and scalability. Furthermore, experimental validation demonstrates strong agreement with simulation results, reinforcing the reliability and practical applicability of the proposed methodology.

Overall, this research establishes a scalable and high-fidelity simulation paradigm that bridges the gap between theoretical modeling and real-world implementation, offering a powerful tool for the design and optimization of next-generation aerospace radome systems and MEMS devices.
