Abstract
In this paper, we propose a new type of lossless metamaterial whose effective permittivity is tunable from negative to positive values. Its optical response is studied analytically and numerically. We further demonstrate that this tunable metamaterial can significantly modulate the phase of an incident pulse with negligible reflection loss, functioning as an efficient phase shifter.
