- Optical design of reflectionless complex media by finite embedded coordinate transformationsMarco Rahm
Center for Metamaterials and Integrated Plasmonics, Department of Electrical and Computer Engineering, Duke University, Durham, North Carolina 27708, USA
Phys Rev Lett 100:063903. 2008..We apply the method to the design of several devices, including a parallel beam shifter and a beam splitter, both of which are reflectionless and exhibit unusual electromagnetic behavior as confirmed by 2D full-wave simulations...
- Transformation-optical design of adaptive beam bends and beam expandersM Rahm
Department of Electrical and Computer Engineering, Center for Metamaterials and Integrated Plasmonics, Duke University, Durham, NC 27708, USA
Opt Express 16:11555-67. 2008..Furthermore, the design of an adaptively adjustable transformation-optical beam expander/compressor is presented. It is observed that a pure transformation-optical design cannot result in a reflectionless beam expander/compressor...
