High-efficiency waveguide couplers via impedance-tunable transformation optics
Jun Cao, Lifa Zhang, Weifeng Jiang +2
We design compact waveguide couplers via impedance-tunable transformation optics. By tuning impedance coefficients in the original space, two-dimensional metallic and dielectric wa…

Reflectionless design of optical elements using impedance-tunable coordinate transformation
Jun Cao, Lifa Zhang, Senlin Yan +1
We report a new strategy to remove the reflections resulted from the finite embedded transformation-optical design by proposing an impedance-tunable coordinate transformation, on w…
