Abstract:

We present a simple and cheap approach to fabricate large-area stopband filters and mirrors for the THz range. This approach extends the well known concept of dielectric mirrors to the far-infrared. We use alternating layers of different materials to build a flexible all-plastic mirror. The films with a typical thickness of several tens of micrometers are arranged to form pairs of quarter-wavelength-layers. The structures are characterized by THz time-domain spectroscopy. The experimental results are in good agreement with transfer matrix simulations.
