However, the pixel density of the film can be straightforwardly reduced by fabricating smaller array spacing and a smaller antenna size, as well as using a more tightly focusing lens for recording.
但是，薄膜的像素密度会由于通造更小的阵列间距和更小的晶须尺寸以及使用更精密的聚焦透镜等直接降低。

We adopted Gaussian beam, ray tracing and vector diffraction integration together to analyze single beam spot-focusing lens antenna.
本文采用将高斯波束法，射线追迹和矢量衍射积分相结合的方法来分析单波束的点聚焦透镜天线。

For the focusing current distribution over the antenna aperture, the authors have got the field distribution diagrams of the focus and around it.
