smooth-wall waveguide 滑壁波导管
This leads to transformation formulas for the connecting boundary of the dielectric ring loaded waveguide and smooth walled waveguide.
导出了介质环加载波导与光壁波导连接处的模转换计算公式。
More unusual, certainly at this price point, is the tweeter which is equipped with an aluminum phase plug, and ACTS as a waveguide to smooth response and further widen high frequency coverage.
更不寻常的当然是在此价位上，高音配备了一个铝制的相位平衡器，并且它起到了一个使波形平滑的作用，进一步加宽的高频范围。
