← ScienceWhich risk increases when microwave waveguide flange surfaces degrade?
A)Field discontinuities induce arcing✓
B)Attenuation from increased skin effect
C)Material fatigue in waveguide walls
D)Ferrite isolator saturation rapidly increases
💡 Explanation
Field discontinuities induce arcing because decreased surface area creates exponentially amplified electric fields initiating dielectric breakdown within the waveguide; therefore arcing is the risk, rather than attenuation or saturation which depend on bulk properties.
