论文摘要

基于变换光学(TO),本文使用几何划分和线性坐标转换来设计缩小的转换 - 重塑,放大转移 - 并重塑设备。提出的设备可以重塑核心区域内包裹的对象的大小和位置。缩小的转移设备将较大的物体缩小到较小的物体并将其转移到不同的位置,而收缩的重新拍摄设备可以生成一个较小的图像,其形状位于不同位置。与以前设计的收缩设备相反,所提出的核心区域内包裹的真实对象和转换对象包含相同的材料属性,而位置变为也是另一个功能。在这里,转移区域位于物理空间边界内,以实现所提出的设备的非负,均质和各向异性材料的属性,对于实际实现而言,这更容易。因此,我们通过放大转移和归功设备进一步验证了这一概念,用于将较小对象视觉转换为位于不同位置和位置的较大对象。我们还应用主动散射器来进一步验证所提出的设备的工作功能。另外,在没有任何散射器的情况下,提议的设备的表现就像集中器和 /或旋转器效应。我们的发现突出了TO的作用,提出了未来对双功能设备进行研究的指导,这些设备将有助于缩小和放大设备,幻觉光学,伪装和对象保护等。 关键字:放大,重塑,收缩,转换光学,隐形斗篷

Based on transformation optics (TO), this paper uses geometric divisions and linear coordinate transformations to design shrinking-shifting - and reshaping, and amplifying-shifting - and reshaping devices. The proposed devices can reshape the sizes and locations of the wrapped-objects inside the core-region. The shrinking-shifting device shrinks the larger object into a smaller one and shifts it to different location, whereas the shrinking-reshaping device can generate a smaller-size image with different shape located at different location. In contrast to previously designed shrinking devices, the real object wrapped inside the proposed core-region and the transformed object contains the same material properties, and the location-shifting is another feature. Here, the shifting-region is located inside the physical-space boundaries to achieve the non-negative, homogeneous, and anisotropic material properties of the proposed device, which are easier for real implementations. Thus, we further verified this concept with the amplifying-shifting and -reshaping devices for visually transformation of smaller object into bigger one placed at different location and position. We also applied active scatterer to further validate the working functionality of proposed devices. In addition, the proposed devices behave like the concentrator and or rotator effect in the absence of any scatterer. Our findings highlight the role of TO, suggesting directions for future research on bi-functional devices that will be useful for shrinking and amplifying devices, illusion optics, camouflage, and object protection etc. Keywords: amplifying, reshaping, shrinking, transformation optics, invisibility cloaks
