← ScienceWhich effect results when a microwave waveguide sustains damage?
A)Reduced guided wave signal strength✓
B)Increased waveguide characteristic impedance
C)Elevated waveguide operating temperature
D)Enhanced guided wave cutoff frequency
💡 Explanation
A deformation introduces losses, therefore the guided wave's amplitude decays rapidly because scattering increases due to impedance mismatch, rather than impedance increasing or any change to the cutoff which remains consistent.
