Structural Design for EMI Shielding: From Underlying Mechanisms to Common Pitfalls.

Area of Science:

• Materials Science
• Electrical Engineering
• Physics

Background:

• Modern civilization depends on advanced electronics, which generate electromagnetic interference (EMI).
• EMI poses a significant threat, necessitating effective shielding solutions.
• Current nanotechnological shielding efforts often overlook absorption-dominant designs.

Purpose of the Study:
