← ScienceWhich risk increases when a dielectric waveguide becomes physically deformed?
A)Increased signal propagation delay
B)Reduced parasitic capacitance effects
C)Enhanced intermodal interference✓
D)Decreased dielectric molecular polarization
💡 Explanation
Deformation changes dimensions, thus affecting refractive index profiles. This induces greater differential mode delay through intermodal interference, because signals take different paths. Therefore, interference is amplified rather than minimizing signal propagation delay, because the mode structure is affected.
