Question
To work as a sensor, Q factor of metamaterial absorber should be Low high both a and b none of these
Solution
The Q factor of a metamaterial absorber should be low to work as a sensor. The Q factor or Quality factor represents the energy loss within a resonator system. If the Q factor is high, it means the system is low loss (or high "quality"). But for sensor applications, we want the system to be sensitive to changes in the environment, which means we want a higher loss system, or a lower Q factor.
