← ScienceWhich condition maximizes power transfer in metamaterial waveguides?
A)Impedance matching condition is satisfied✓
B)Refractive index becomes strongly negative
C)Band gap frequency matches signal
D)Permittivity approaches a finite maximum
💡 Explanation
Maximum power transfer occurs due to impedance matching, because the input impedance equals waveguide impedance, leading to minimum reflection and maximum transmission. Therefore, impedance matching maximizes power transfer, rather than specific refractive index, bandgap alignment, or permittivity values unless impedance matches.
