    • Near-field electromagnetic devices having an opaque metallic screen with a fractal iterate aperture are provided. More specifically, the aperture is obtained by application of a self-similar replacement rule to an initial shape two or more times. Alternatively, the aperture can be obtained by application of a self-similar replacement rule one or more times to an initial C-shape. Such apertures tend to have multiple transmission resonances due to their multiple length scales. Fractal iterate apertures can provide enhanced transmission and improved spatial resolution simultaneously. Enormous improvement in transmission efficiency is possible. In one example, a checkerboard fractal iterate aperture provides 1011 more intensity gain than a square aperture having the same spatial resolution. Efficient transmission for fractal iterate apertures having spatial resolution of λ/20 is also shown. The effect of screen thickness and composition can be included in detailed designs, but do not alter the basic advantages of improved transmission and spatial resolution provided by the invention.
    • 提供具有分形迭代孔径的不透明金属屏幕的近场电磁装置。 更具体地,通过将​​自相似的替换规则应用于初始形状两次或更多次来获得孔径。 或者,可以通过将自相似替换规则一次或多次应用于初始C形来获得孔径。 这样的孔由于其多个长度尺度而倾向于具有多个传输谐振。 分形迭代孔径可以同时提供增强的传输和改进的空间分辨率。 传输效率的巨大提高是可能的。 在一个示例中,棋盘分形迭代孔径具有比具有相同空间分辨率的方形孔径更多的强度增益10 11。 还示出了具有λ/ 20的空间分辨率的分形迭代孔的有效传输。 屏幕厚度和组成的效果可以包括在详细的设计中,但不改变本发明提供的改进的传输和空间分辨率的基本优点。
