Circle-shaped Transformation Cavity via Center-Shift Möbius Transfomation
Jinhang Cho, Inbo Kim, Sunghwan Rim +3
Circle-shaped transformation cavities of shifted center are the most simple transformation cavities in the sense that they have only spatial index variation without boundary shape…
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…
Abnormal high- modes of coupled stadium-shaped microcavities
Jung-Wan Ryu, Soo-Young Lee, Inbo Kim +3
It is well known that the strongly deformed microcavity with fully chaotic ray dynamics cannot support high-Q modes due to its fast chaotic diffusion to the critical line of refrac…
Outer Resonances and Effective Potential Analogy in Two-Dimensional Dielectric Cavities
Jinhang Cho, Inbo Kim, Sunghwan Rim +2
Outer resonances are studied as one type of quasinormal modes in two-dimensional dielectric cavities with refractive index . The outer resonances can be verified as the resona…
Origin of the Transition Inside the Desynchronized State in Coupled Chaotic Oscillators
Chil-Min Kim, Won-Ho Kye, Sunghwan Rim +4
We investigate the origin of the transition inside the desynchronization state via phase jumps in coupled chaotic oscillators. We claim that the transition is governed by type-I in…
