← ScienceWhich outcome occurs when high-power microwaves exceed waveguide's dielectric strength?
A)Dielectric breakdown and arc formation✓
B)Increased signal propagation velocity
C)Harmonic frequency resonance stabilization
D)Reduced conductive losses sidewall currents
💡 Explanation
Dielectric breakdown occurs because the electric field component the microwave exceeds waveguide material strength causing ionization. This leads to arcing/sparking rather than faster propagation; therefore breakdown is the consequence, rather than harmonic stabiliziation or reduced losses.
