On the quality factor of a low-loss parallel-plate resonator based on complementary metamaterials
Author
Summary, in English
Several proposals have been made during the last ten years on size-independent resonators by using metamaterials
for phase compensation. In this paper, we present an estimate of the quality factor of a simple
parallel-plate resonator, based on realistic assumptions such as linear, passive, causal, time-translational
invariant metamaterials, and lossy walls. It is found that the quality factor of the resonator depends on
whether the losses of the material or the metal walls are dominating: in the former case, there is no size
dependence, in the latter case, the size dependence is similar to a vacuum-lled resonator.
