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…
