Boundary integral equation method for resonances in gradient index cavities designed by conformal transformation optics
Jung-Wan Ryu, Jinhang Cho, Soo-Young Lee +5
In the case of two-dimensional gradient index cavities designed by the conformal transformation optics, we propose a boundary integral equation method for the calculation of resona…

Optimization of conformal whispering gallery modes in limaçon-shaped transformation cavities
Jung-Wan Ryu, Jinhang Cho, Inbo Kim +1
In limaçon-shaped gradient index dielectric cavities designed by conformal transformation optics, the variation of Q-factors and emission directionality of resonant modes was trace…
