Maxwell Fish接目镜的完美排水口

Perfect drain for the Maxwell Fish Eye lens

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

摘要:

使用Maxwell鱼眼(MFE)对电磁波进行完美成像需要一个新的概念:完美漏极。从数学的角度来看,一个完美的点漏就像一个理想的点源,除了它从电磁场的功率消耗,而不是产生它。我们在这里表明,完美的漏MFE可以被看作是一个耗散区域的直径趋于零。然而,该区域的复介电常数$\varepsilon$不能取任意值,因为它取决于漏极的大小以及频率。这种对完美漏极的解释与电磁理论的中心概念有很好的联系。这开启了计算机模拟中的建模和完美排水的实验验证。

英文摘要:

Perfect imaging for electromagnetic waves using the Maxwell Fish Eye (MFE) requires a new concept: the perfect drain. From the mathematical point of view, a perfect point drain is just like an ideal point source, except that it drains power from the electromagnetic field instead of generating it. We show here that the perfect drain for the MFE can be seen as a dissipative region the diameter of which tends to zero. The complex permittivity $\varepsilon$ of this region cannot take arbitrary values, however, since it depends on the size of the drain as well as on the frequency. This interpretation of the perfect drain connects well with central concepts of electromagnetic theory. This opens up both the modeling in computer simulations and the experimental verification of the perfect drain.
