← ScienceWhich risk increases when high-power microwaves enter conductive enclosures?
A)Dielectric breakdown within integrated circuits
B)Resonance causing localized voltage amplification✓
C)Antenna detuning due to surface currents
D)Thermal runaway in poorly shielded transformers
💡 Explanation
Input of microwaves can cause resonance phenomenon within the enclosure, therefore it amplifies the voltage, creating hotspots. It's confined rather than causing dielectric breakdown directly; choice A is a slower degradation under constant lower field, and others don't leverage wave proopagation.
