This boundary condition also means that the magnetic field is zero in the normal direction to the boundary. That is, the magnetic field must be tangential to this boundary. As a consequence, this boundary condition has the physical interpretation of a boundary through which current can only flow...
Hi all, I am new to Comsol and am trying to model a simple 2D composite unit cell (concentric circle in a square) with periodic boundary conditions. As a guide I am using a paper by Drago et al. (dx.doi.org/10.1016/j.compscitech.2006.02.031). In this paper, the symmetry of th...
These include Symmetry, Symmetry Plane, and Antisymmetry boundary conditions, among other types of symmetry boundary conditions (e.g., Sector Symmetry), which enable you to specify the symmetry planes or lines of symmetry in your model.The Symmetry boundary condition that is used in the Shell-...

The transmittance spectra of α-MoO3 structures and corresponding field distributions were simulated by finite-element methods using COMSOL Multiphysics. The simulations were performed on unit cells whose configurations were detailed in the main text. Periodic boundary conditions were set up at the side...
(COMSOL Multiphysics 5.4). The symmetry-broken SSP was sub-divided into very small but finite size meshes, and each mesh is governed by a set of characteristic equations which describe its physical properties and boundary conditions. Although there is no general closed form solution of the ...
The FEM-based eigenfrequency analysis method (COMSOL Multiphysics) is utilized and the calculated results are shown in Fig. 2. Figure 2(a) manifests the large frequency splitting of the PCNC pairs when placed closely. When the gap is 100 nm, the frequency detuning is as high as 2.22...
All numerical experiments were performed by Finite Element simulations using the commercial software COMSOL Multiphysics® 6.1 (build 357). The balance of linear momentum in the form of Eq. (3)\(_1\), along with the zero force boundary condition at the endpoint \(s=1\), allows to compute...
The near-field interference images were simulated by the finite element method using COMSOL Multiphysics. The electric field distribution of plain α-MoO3 shown in the inset of Fig. 2d was excited by a vertically polarized dipole source. In the simulations of PoCs, we considered a 3 × ...
