The rapid proliferation of small satellites, like CubeSats, intensifies electromagnetic compatibility (EMC) challenges in the demanding aerospace environment. This work is an initial attempt to investigate the use of wood-based structure as an effective and sustainable electromagnetic (EM) shielding material for these constrained platforms. A standard 1U CubeSat geometrical model was designed using the High Frequency Structure Simulator (HFSSTM) software. Using the Finite Element Method (FEM) for three-dimensional full-wave electromagnetic structure analysis, the electric field behavior and the shielding effectiveness (SE) of the proposed wood-based shielding materials were simulated. The research demonstrates the viability of this approach, analyzing the shielding mechanisms and effectiveness of wood structure across relevant operational frequencies. The findings position wood as a promising, alternative material solution for space-system electromagnetic shielding design.
