1Mapping an on-chip terahertz antenna by a scanning near-field probe and a fixed field-effect transistor显示文摘In the terahertz(THz) regime,the active region for a solid-state detector usually needs to be implemented accurately in the near-field region of an on-chip antenna.Mapping of the near-field strength could allow for rapid verification and optimization of new antenna/detector designs.Here,we report a proof-of-concept experiment in which the field mapping is realized by a scanning metallic probe and a fixed AlGaN/GaN field-effect transistor.Experiment results agree well with the electromagnetic-wave simulations.The results also suggest a field-effect THz detector combined with a probe tip could serve as a high sensitivity THz near-field sensor.吕利 孙建东 Roger A.Lewis 孙云飞 吴东岷 蔡勇 秦华 2015Chinese Physics B2015,24,2:0
