← ScienceWhich risk significantly worsens when metallic shielding obstructs microwave communication?
A)Reduced signal penetration power✓
B)Increased capacitive voltage limit
C)Increased transmission phase velocity
D)Decreased resonant cavity bandwidth
💡 Explanation
Signal loss increases due to skin effect; metallic shielding attenuates waves via eddy current dissipation, limiting propagation. Shielding causes energy absorption and reflection, rather than increased penetration because the primary mechanism is attenuation, therefore signal strength decreases.
