“…The grid size is set to be 10 times smaller than the dimensions of the corresponding regions and the maximum mesh element size is set to be 20 nm, such that accurate simulation results can be achieved within the allowed time and computational resources. Perfect matched layers (PMLs) were also added at the outer edges of the FEM simulation window to approximate an open geometry [ 28 ]. The PML was positioned 0.6 μm away from the waveguide edge.…”

We propose a compact 1-μm-radius microring resonator sensor based on a hybrid plasmonic waveguide on a silicon-on-insulator substrate. The hybrid waveguide is composed of a metal-gap-silicon structure, where the optical energy is greatly enhanced in the narrow gap. We use the finite element method to numerically analyze the device optical characteristics as a biochemical sensor. As the optical field in the hybrid micoring resonator has a large overlap with the upper-cladding sensing medium, the sensitivity is very high compared to other dielectric microring resonator sensors. The compactness of the hybrid microring resonator is resulted from the balance between bending radiation loss and metal absorption loss. The proposed hybrid microring resonator sensors have the main advantages of small footprint and high sensitivity and can be potentially integrated in an array form on a chip for highly-efficient lab-on-chip biochemical sensing applications.

“…As the tangential vector finite element method (TVFEM) can cope with material discontinuities as well as sharp edges and corners in a natural way, it has been widely applied in the analysis of electromagnetic problems and has gained great success [1–4]. In the past few decades, the lowest order basis, i.e., Whitney basis [5], has been thoroughly investigated and widely used in the analysis of electromagnetic devices.…”

In this article, hierarchical finite element method (FEM) based on curvilinear elements is used to study three-dimensional (3D) Figure 5 Measured results of IMD3 for the fixed uneven DPA and the proposed optimum uneven DPA.

The incomplete Cholesky preconditioned loose generalized minimal residual solver (LGMRES) based on decomposition algorithm (DA) is applied to solve the FEM equations. The efficiency of the proposed approach is studied on several numerical problems. Numerical results demonstrate that the DA-based LGMRES is especially effective when the hierarchical FEM is used to solve 3D electromagnetic problems.
