我们提出并制作了一种产生涡旋波的共振隧穿二极管（RTD）太赫兹振荡器。RTD集成在衬底上的十字槽中，径向线缝隙天线（RLSA）被放置在RTD周围。RTD的输出从十字槽入射到衬底中，并从RLSA以涡旋波的形式发射。在所制造的振荡器的测量的辐射图案中，在中心轴上观察到输出强度的下降，这是涡旋波的特征。
We have proposed and fabricated a resonant-tunneling-diode (RTD) THz oscillator that generates a vortex wave. The RTD is integrated in the cross slot on the substrate, and a radial line slot antenna (RLSA) is spirally placed around the RTD. The output of RTD is incident from the cross slot into the substrate, and emitted from the RLSA as a vortex wave. In the measured radiation pattern of the fabricated oscillator, a dip of the output intensity was observed on the central axis, which is a feature of the vortex wave.
