Stimulated Smith-Purcell emission based on bound states in the continuum
Zhaofu Chen, Renjun Yang, Xiaohan Sun
Recent advances in the development of bound states in the continuum offer new strategies to tailor electron-wave interaction and hence control the electron-induced emission. In thi…

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…
