用开态直流电阻率和关态电容表征了直接光激励下的GeTe基射频开关。基于我们的紧耦合偶极子阵列，在高达60度的宽扫描角度上具有超过4到1带宽的性能，并具有使用可重构巴伦的带内抑制能力，天线孔径通过集成光控基于GETE的射频开关展示了重构灵活性。
Characterization of GeTe-Based RF Switches under direct optical laser excitation is shown with the ON state DC electrical resistivity and OFF state capacitance. Based on our tightly-coupled dipole array with performance in excess of 4 to 1 bandwidth over wide-scan angle up to 60 degrees, and with in-band rejection capability using reconfigurable baluns, the antenna aperture is shown to exhibit reconfiguration flexibility with the integration of optically-controlled GeTe-Based RF switches.
