Whispering gallery modes in triple microdisks of triangular configurations
Jung-Wan Ryu, Sunghwan Rim
We study whispering gallery modes in triple microdisks of equilateral and isosceles triangular configurations. The characteristic properties of resonant modes in three microdisks o…
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…
Oscillation death in coupled counter-rotating identical nonlinear oscillators
Jung-Wan Ryu, Woo-Sik Son, Dong-Uk Hwang
We study oscillatory and oscillation suppressed phases in coupled counter-rotating nonlinear oscillators. We demonstrate the existence of limit cycle, amplitude death, and oscillat…
Emergent localized states at the interface of a twofold -symmetric lattice
Jung-Wan Ryu, Nojoon Myoung, Sungjong Woo +3
We consider the role of non-triviality resulting from a non-Hermitian Hamiltonian that conserves twofold PT-symmetry assembled by interconnections between a PT-symmetric lattice an…
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…
