Switching between perfect absorption and polarization conversion, based on hybrid metamaterial in the GHz and THz bands
We demonstrate a multifunctional metamaterial (MM) structure which can behave like a perfect absorber (PA) or polarization converter (PC) by controlling the lumped varactor. In PC mode, the MM revealed cross-polarization conversion in a frequency range from 2.0 to 7.0 GHz with a polarization-convers...
