Sammanfattning

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.
