Paragraph starter
The comparative analysis of electromagnetic shielding effectiveness between solid copper plates and copper composite fabrics reveals that solid copper offers superior performance due to its isotropic nature, maintaining effectiveness across various frequencies and orientations. Composite fabrics, conversely, exhibit anisotropic behavior and a decline in shielding effectiveness at higher frequencies, attributed to structural gaps. This suggests that for critical applications demanding consistent and high-level electromagnetic interference mitigation, solid metal materials are a more reliable choice.
