对工作在w波段的宽带多层微波窗进行了数值模拟和构造，并对其微波特性进行了测量。窗户的作用是把真空和大气分开。它必须满足宽带、低反射和高机械强度的陀螺放大器应用的严格要求。该窗口在90-100 GHz范围内显示${- 20}~{\rm dB}$反射（两个小区域除外），这与本文给出的数值模拟结果很好地吻合。
A broadband multi-layer microwave window operating in the W-band frequency range was numerically simulated, constructed and its microwave properties measured. The window acts to separate vacuum and atmosphere. It had to meet strict requirements for application in gyro-amplifiers of broadband, low reflection and high mechanical strength. The window was manufactured showing a ${- 20}~{\rm dB}$ reflection over 90–100 GHz (except in two small regions), which is in good agreement with the numerical simulation presented in this letter.
