Juan C. Gonzalez, Pablo Benitez, Juan C. Minano, Dejan Grabovickic

摘要:

负折射透镜(NRL)已经表明,光学系统可以产生细节低于经典阿贝衍射极限的图像。该光学系统将由物体表面发射的电场传输到图像表面,在两个表面中产生相同的场分布。特别地,物表面中的狄拉克δ电场被聚焦而不受像表面中的狄拉克δ电场的衍射限制。Maxwell鱼眼接目镜(MFE)和球面短程线波导(SGW)已经被声称使用具有不同含义的正折射来突破衍射极限。在这些情况下,已经考虑了从点源到点接收器的功率传输,当接收器从焦点移位远小于波长的距离时,功率传输急剧下降。虽然这些系统可以检测高达波长/500的位移,但它们不能与NRL进行比较,因为物体和图像表面的概念尚未建立。在这里,它提出了一个分析的SGW与定义的对象和图像表面。结果表明,物体表面的狄拉克δ电场在像面上产生低于折射极限的像。

英文摘要:

Negative Refractive Lens (NRL) has shown that an optical system can produce images with details below the classic Abbe diffraction limit. This optical system transmits the electric field, emitted by the object surface, towards the image surface producing the same field distribution in both surfaces. In particular, a Dirac delta electric field in the object surface is focused without diffraction limit to the Dirac delta electric field in the image surface. The Maxwell Fish Eye lens (MFE) and the Spherical Geodesic Waveguide (SGW) have been claimed to break the diffraction limit using positive refraction with a different meaning. In these cases, it has been considered the power transmission from a point source to a point receptor, which falls drastically when the receptor is displaced from the focus by a distance much smaller than the wavelength. Although these systems can detect displacements up to Wavelength/500, they cannot be compared to the NRL, since the concept of the object and image surface is not established. Here, it is presented an analysis of the SGW with defined object and image surfaces. The results show that a Dirac delta electric field on the object surface produces an image below the refraction limits on the image surface.
