Tunabilty of terahertz metamaterials using liquid crystal

Impact of laser polarization and angle of incidence on phase shifting efficacy of an all-optically addressed liquid crystal delay line at X band

“…The insertion loss dependency on polarizations and incident angles will be investigated and reported in our later papers, based on which we can conclude the overall performance comparison with other stimuli, e.g., applying a magnetic field [8], temperature field [9], as well as the mainstream electrical field biasing [10] [11]. Upscaling techniques from microwave to millimeterwave [12] and terahertz [13] will also be undertaken in future endeavors as inspired by the upcoming 6G [14] and intelligent reflective surfaces [15] that advance at a rapid pace. Meanwhile, future research can examine the behavior of the laser-induced functional threshold (LIFT) and laser-induced damage threshold (LIDT) at sub-LIDT fluences under multi-pulse irradiation settings [16].…”
