In this work, we propose that one-dimensional ultratransparent dielectric photonic crystals with wide-angle impedance matching and shifted elliptical equal frequency contours are promising candidate materials for illusion optics. The shift of the equal frequency contour does not affect the refractive behaviors, but enables a new degree of freedom in phase modulation. With such ultratransparent photonic crystals, we demonstrate some applications in illusion optics, including creating illusions of a different-sized scatterer and a shifted source with opposite phase. Such ultratransparent dielectric photonic crystals may establish a feasible platform for illusion optics devices at optical frequencies.
在这项工作中，我们提出具有广角阻抗匹配和偏移椭圆等频线的一维超透明介电光子晶体是用于幻象光学的有前景的候选材料。等频线的偏移不会影响折射行为，但能在相位调制方面提供一个新的自由度。利用这种超透明光子晶体，我们展示了在幻象光学中的一些应用，包括制造不同尺寸散射体和具有相反相位的偏移源的幻象。这种超透明介电光子晶体可能为光频下的幻象光学器件建立一个可行的平台。
