对zemax光源模型中的二极管光源进行了参数的总结与简要的介绍，里面缺少了像散的描述，具体请看博文https://allen928.blog.csdn.net/article/details/118514858，补充了像散的计算方法

提出了一种具有图案可重构性的宽带印刷锥形缝隙天线。 天线由四个锥形槽，一个可重新配置的微带到槽线过渡和四个引脚二极管组成。 通过适当布置偏置电压，可以通过简单的偏置电路实现四个端射辐射图。 测得的相对阻抗带宽为| S11 | 小于-10 dB为71.3％，在所有工作模式下为1.57至3.31 GHz。 在中心频率为2.4 GHz时，四个方向的增益均高于6.4 dBi。 实测结果与模拟结果吻合良好。 所提出的天线在宽带的四个可重新配置方向上具有良好的性能。

We propose and demonstrate a scheme to measure the distribution of temperature along an optical fiber based on pseudo-random sequence modulation. In our experimental work, current modulation with a pseudo-random bit sequence (PRBS) is applied to a laser diode that serves as the Brillouin pump light and reference light. Because of the independence of the spatial resolution on the PRBS length, the measurement range can be extended while maintaining high spatial resolution using a long PRBS length.

A novel diode-clamped carrier stored trench bipolar transistor (CSTBT) with improved performances is proposed. The improvement has been achieved by introducing a P-layer region under the trench gate, which is connected to the cathode electrode through two integrated series diodes. In the blocking-state, almost all of the reverse voltage is sustained by Player/N-drift junction, which makes the doping concentration of the carrier stored layer is independent of the breakdown voltage,thus overcoming
