Validation of Shielding Properties of the Electromagnetic Absorber Materials Through Electromagnetic Simulation

This paper addresses the electromagnetic characterization of Electromagnetic Absorber Material (EAM) through numerical simulation. A resonant-type EAM is analyzed using Reflection Loss (RL) as the key performance parameter. Two representative measurement configurations, an APC-7 connector and a free-space setup, are defined and modeled to replicate typical experimental arrangements. The simulations are carried out using Ansys HFSS, based on the Finite Element Method (FEM), enabling controlled analysis of material behavior while overcoming mechanical and geometrical limitations inherent to conventional measurement techniques.
