← ScienceWhich outcome occurs if a dielectric shifts excessively due to mechanical resonances in a capacitive waveguide under high power microwave transmission?
A)Parametric amplification is significantly altered.
B)Increased waveguide temperature and attenuation.✓
C)Reflected power at the input decreases.
D)Microwave carrier frequency band broadens.
💡 Explanation
Excessive dielectric shift causes increased waveguide temperature and attenuation because dielectric losses induce **dielectric heating**. This occurs if the shift is induced by mechanical resonances, leading to more loss. Therefore, B is correct; rather than power reflection changes.
