Example Sentences:

	1.	Similarly , the paper also makes an analysis of the effect that the truncation error of finite scanning has upon the far - field pattern and then introduces the consequent method of compensation 随后分析了扫描面截断误差对远场方向图的影响，并给出了相应的补偿方法。
	2.	Compared with the effect of mutual coupling to general antenna arrays , chebyshev - dolph antenna arrays , schelkunoff super - derective arrays and chebyshev - dolph super - derective 比较了互耦对等幅同相天线阵、 chebyshev - dolph天线阵、 schelkunoff阵和chebyshev - dolph超方向性阵天线远场方向图的影响。
	3.	As another aspect of the applications of this method , the scatted electromagnetic field of the fractal rough surface is analyzed , and the relationship between the fractal dimension and the pattern of the scattering coefficient is su mmarized 最后还利用辅助场fdtd方法分析了粗糙表面的散射电磁场，指出散射场方向图与海面形状的关系。
	4.

	5.	A patch antenna with air holes in the substrate has been designed . the finite - difference time - domain ( fdtd ) method together with the perfectly matched layer ( pml ) boundary treatment has been used to study the performance of the antenna . it is shown that the surface waves are significiently suppressed , the frequency bandwidth is improved , the sidelobe levels are reduced and consequently the gain in the forward direction is improved by 14 db ( about 4 db higher than the value reported previously ) 设计了一种基底钻周期圆孔结构的电磁(光子)晶体贴片天线，用fdtd方法并结合pml吸收边界条件对该天线进行了研究，结果表明本文所设计的基底钻孔型电磁晶体贴片天线取得了多方面的性能改善，与普通天线相比，基底中的表面波受到很大抑制，天线的带宽增加，远场方向图上天线的旁瓣和背瓣被明显削弱，向前辐射的增益由原来的12db增加到26db ，增加了14db ，比文献上报道的gonzalo等人的研究结果提高了4db 。
