基于复坐标变换光学的PT超材料

PT Metamaterials via Complex-Coordinate Transformation Optics

Giuseppe Castaldi, Silvio Savoia, Vincenzo Galdi, Andrea Alu', Nader Engheta

摘要:

我们扩展的变换光学范式到一个复杂的空间坐标域,以处理电磁超材料的特点是平衡的损耗和增益,特别强调宇称时间(PT)对称的超材料。我们将这一一般理论应用于复源点辐射和各向异性透射共振,说明了我们的方法在系统设计,分析建模和物理洞察复杂坐标波对象和共振状态方面的能力和潜力。

英文摘要:

We extend the transformation-optics paradigm to a complex spatial coordinate domain, in order to deal with electromagnetic metamaterials characterized by balanced loss and gain, giving special emphasis to parity-time (PT) symmetric metamaterials. We apply this general theory to complex-source-point radiation and anisotropic transmission resonances, illustrating the capability and potentials of our approach in terms of systematic design, analytical modeling and physical insights into complex-coordinate wave-objects and resonant states.
