← ScienceWhich mechanism prevents total power transmission across unmatched waveguides?
A)Reflected wave interference alters impedance✓
B)Reactive loading dissipates resonant energy
C)Eddy current losses increase attenuation
D)Dielectric breakdown induces mode conversion
💡 Explanation
Impedance mismatches cause reflections. Reflected wave interference superimposes on the input wave altering the characteristic impedance of the transmission line because the superposition creates standing waves; therefore less power is transmitted, rather than alternative energy dissipations.
