摘要

为了提高W波段的微波透过率，设计制作了三角形结构的槽板。利用有效介质理论(EMT)和时域有限差分(FDTD)程序对三角结构的参数进行了优化。对W波段增透表面进行了实验室验证，实验结果与理论结果定性一致。

Improvement of transmittance using groove structured surface for microwave imaging diagnostics in tokamak plasmas

Groove plate with triangle structure has been designed and fabricated to improve the microwave transmittance in W band. The parameters of the triangle structure has been optimized via the Effective Medium Theory (EMT) and FDTD program. The antireflection surface in W band has been verified in lab, the experimental results are qualitatively consistent with the theoretical results.
