带有凹槽反射镜的波导斜折弯被用来改变超大尺寸的波导中的偏振。凹槽增加了反射镜上的欧姆损耗，并且这种增加是入射和输出偏振的函数。本文将欧姆损耗的理论计算与其他已有的理论和实验数据进行了比较。从理论上确定了使最大欧姆损耗最小的偏振片斜面弯曲的最佳方向和位置。然后，利用欧姆损耗的理论计算和Ansys对镜面冷却的模拟，评估了偏振器斜接弯头处理ITER热负荷的能力。
Waveguide miter bends with grooved mirrors are used to alter the polarization in oversized waveguides. The grooves increase the ohmic loss on the mirrors, and this increase is a function of the incident and output polarizations. In this paper, theoretical calculations of ohmic loss are compared with other available theory and experimental data. The optimum orientation and location of the polarizer miter bends for the lowest maximum ohmic loss is determined from the theory. Then the capability of polarizer miter bends to handle the heat loading at ITER is evaluated, using theoretical calculations of the ohmic loss and ANSYS modeling of the mirror cooling.
