设计、制造和测试了一种金属网消色差半波片（HWP），它可能用于毫米和亚毫米天文仪器。这里提出的原型设备是基于12网格Shatrow [IEEE Trans.Propag. 43，109（1995）]的配方，以在120-180 GHz的频率范围内操作。传输线建模和有限元分析[Ansoft HFSS网站：http：//www.ansoft.com/hfss/]用于根据作为频率的函数的器件传输、反射、吸收、相移和交叉偏振来优化设计几何参数。由此产生的原型设备的构造和使用偏振傅里叶变换光谱仪的非相干辐射，以探索其频率和偏振行为的特征。这些测量结果与模型非常吻合。列出了所获得的HWP性能特性。
A metal-mesh achromatic half-wave plate (HWP) has been designed, manufactured, and tested for potential use in millimeter and submillimeter astronomical instruments. The prototype device presented here is based on a 12-grid Shatrow [IEEE Trans. Antennas Propag. 43, 109 (1995)] recipe to operate over the frequency range of 120-180 GHz. Transmission line modeling and finite-element analysis [Ansoft HFSS website: http://www.ansoft.com/hfss/] were used to optimize the design geometrical parameters in terms of the device transmission, reflection, absorption, phase-shift, and cross-polarization as a function of frequency. The resulting prototype device was constructed and characterized using incoherent radiation from a polarizing Fourier transform spectrometer to explore its frequency and polarization behavior. These measurements are shown to be in excellent agreement with the models. Lists of the achieved HWP performance characteristics are reported.
