← ScienceWhich risk increases when high-frequency electromagnetic waves resonate within a microwave cavity?
A)Rapid formation of plasma arcs
B)Dielectric breakdown accelerates failure✓
C)Increased quantum tunneling probability
D)Ferrimagnetic resonance amplitude reduction
💡 Explanation
Dielectric breakdown risk increases because standing waves create intense electric fields. This field enhancement surpasses dielectric strength, initiating the dielectric breakdown mechanism. Therefore, insulation fails rather than plasma forming, which requires free ions, nor quantum tunneling, which typically happens at very small scales.
