A Semi-definite Optimization Method for Maximizing the Shared Band Gap of Topological Photonic Crystals
Chiu-Yen Kao, Junshan Lin, Braxton Osting
Topological photonic crystals (PCs) can support robust edge modes to transport electromagnetic energy in an efficient manner. Such edge modes are the eigenmodes of the PDE operator…

A finite element contour integral method for computing the resonances of metallic grating structures with subwavelength holes
Yingxia Xi, Junshan Lin, Jiguang Sun
We consider the numerical computation of resonances for metallic grating structures with dispersive media and small slit holes. The underlying eigenvalue problem is nonlinear and t…

Mathematical theory for the interface mode in a waveguide bifurcated from a Dirac point
Jiayu Qiu, Junshan Lin, Peng Xie +1
In this paper, we prove the existence of a bound state in a waveguide that consists of two semi-infinite periodic structures separated by an interface. The two periodic structures…
