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…
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…
Dynamics of Morphology-Dependent Resonances by Openness in Dielectric Disk for TE polarization
Jinhang Cho, Sunghwan Rim, Chil-Min Kim
We have studied the dynamics of morphology-dependent resonances by openness in a dielectric microdisk for TE polarization. For the first time, we report that the dynamics exhibits…
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…
An efficient finite element method applied to quantum billiard systems
Woo-Sik Son, Sunghwan Rim, Chil-Min Kim
An efficient finite element method (FEM) for calculating eigenvalues and eigenfunctions of quantum billiard systems is presented. We consider the FEM based on triangular cont…
