← ScienceWhich outcome occurs when a dielectric material with high permittivity fills the interspace between conductors in the gigahertz electromagnetic resonator?
A)Resonant frequency shifts to lower✓
B)Coupling factor remains unchanged
C)Quality factor increases sharply
D)Waveguide's TE mode strengthens
💡 Explanation
The resonant frequency shifts lower because higher permittivity increases capacitance via increased polarization; therefore, the resonance frequency decreases, rather than maintaining the initial factor or increasing the propagating waveguides’ mode.
