Mirrored Transformation Optics
A mirrored transformation optics (MTO) approach is presented to overcome the material mismatch in transformation optics. It makes good use of the reflection behavior and introduce a mirrored medium to offset the phase discontinuities. Using this approach, a high-performance planar focusing lens of transmission-type is designed, which has large concentration ratio than other focusing lens obtained by generalized Snell law. The MTO will not change any functionality of the original lens and promising potential applications in imaging and light energy harvesting.
