We design a plano-convex lens working in the terahertz(THz) frequency range and fabricate it using threedimensional(3D) printing technology. A 3D field scanner is used to measure its focal properties, and the results agree well with the numerical simulations. The refractive index and absorption coefficient measurements via THz time-domain spectroscopy(THz-TDS) reveal that the lens material is highly transparent at THz frequencies. It is expected that this inexpensive and rapid 3D printing technology holds promise for making various THz optical elements.

8月3日 晴 乡村是我童年最快乐的地方,那儿有花有草,有清澈的河水,有绿油油的田野,美丽极了! 夏天,天气非常炎热。傍晚的时候,小伙伴们都争先恐后地来到河边,迫不及待地跳下河去。那些水性好的孩子们,一会儿沉到河底,一会儿又浮了上来,像小鸭子似的抖动着脑袋上那湿漉漉的头发,手里举着河蚌和贝壳向岸上扔。我看着他们玩得非常开心,也跃跃欲试,终于抵制不了水的诱惑,跳下河去。在水中,自由自在地游着,感觉
