Abstract
We have studied the terahertz response of a dielectric membrane with a high-mobility two-dimensional electron system (2DES) on one side. The developed device exhibits electromagnetic transparency above the plasma frequency that is found to be determined by the 2DES density and membrane thickness. Significantly, we demonstrate the opaque low-frequency region to be highly tunable. Our results can find applications in the area of active terahertz devices.
