Approximate optical cloaking in an axisymmetric silicon photonic crystal structure

Research output: Contribution to journalArticlepeer-review


Axisymmetric photonic crystal structures may be designed to possess interesting optical properties, particularly when the photonic band structure of the material is highly anisotropic. We use finite element calculations to demonstrate an approximate electromagnetic cloaking effect imparted by a structure consisting of concentric silicon photonic crystal layers. The results show that it is possible to bend light around an object by simply using anisotropy. The calculations show that the cloaking mechanism is fundamentally different from Pendry's approach. This design may work as a practical solution for optical cloaking.
