本文介绍了对一种由连续金属环组成的感应网的实验研究，该感应网是通过在石英玻璃上采用紫外光刻技术制造的。实验结果表明，在与方形网相同的周期和线宽下，环形网由于其更高的遮光率而具有更好的透射率，由于其更小的最大孔径而具有更强的电磁屏蔽性能，并且由于其高阶衍射能量的比率更低且分布更均匀而具有更小的成像质量下降。因此得出结论，这种环形网可用作高通滤波器，为光学透明元件提供电磁屏蔽。（c）2007美国光学学会。
This paper presents the experimental study on an inductive mesh composed of contiguous metallic rings fabricated using UV-lithography on quartz glass. Experimental results indicate that, at the same period and linewidth as square mesh, ring mesh has better transmissivity for its higher obscuration ratio, stronger electromagnetic shielding performance for its smaller maximum aperture, and less degradation of imaging quality for its lower ratio and uniform distribution of high order diffraction energy. It is therefore concluded that this kind of ring mesh can be used as high-pass filters to provide electromagnetic shielding of optical transparent elements.
