Abstract

We propose and demonstrate a liquid crystal (LC) based terahertz phase shifter with a thick (550 mu mathrm{m} in total) bi-Iayer LC cell structure incorporating a thin transparent polymeric intermediate layer. The present phase shifter exhibited remarkable performance improvement. The phase shift increased from 94° to 111° threshold and drive voltages decreased from 2.2 mathbf{V-{RMS}} to mathbf{1 V-{RMS}} and from mathbf{10 V-{RMS}} to mathbf{8.4 V-{RMM}}, respectively, in comparison with those for single-layer cell structure.
