| Popis: | A novel two-step method is presented to model thin- or thick-layered homogeneous or periodic structures by replacing them with 2-D sheets, which are solved using shell elements. A unit cell model of the thin/thick 2-D structure is used to extract the circuit $Y$ matrix, which characterizes the layer. The shell elements are modeled by doubling the essential variables on the surface. The link between the two sides of the surface is governed by the circuit $Y$ matrix obtained from the unit cell model. In this way, the shielding effects of complex homogeneous or periodic structures can be accurately and efficiently modeled by using the finite-element method without volumetric meshing of the layer(s). |
