← ScienceWhich consequence results when a metamaterial antenna array suffers delamination?
A)Reduced directive gain observed✓
B)Increased thermal noise floor
C)Decreased amplifier saturation point
D)Elevated second harmonic distortion
💡 Explanation
Delamination changes the effective permittivity profile; therefore, disruption of designed coherent interference for directive gain occurs because the **waveguide impedance mismatch** increases rather than affecting thermal noise. The array will lose gain, rather than modify other antenna parameters.
