Designing scattering-free isotropic index profiles using phase-amplitude equations

15 May 2018 King Chris Horsley Simon Philbin Thomas

The Helmholtz equation can be written as coupled equations for the amplitude and phase. By considering spatial phase distributions corresponding to reflectionless wave propagation in the plane and solving for the amplitude in terms of this phase, we designed two-dimensional graded-index media which do not scatter light...
