Which risk increases when a Faraday cage contains resonant structures under electromagnetic wave exposure?

A)Shielding effectiveness near resonant frequencies
B)Increased power loss in the shields
C)Suppressed electromagnetic interference emission
D)Enhanced skin depth within cage material

💡 Explanation

Shielding fails when resonant structures inside a Faraday cage amplify incoming waves via constructive interference, a form of electromagnetic resonance; because internal fields rise, therefore penetration increases, rather than being attenuated more at resonant frequencies.
