Treating very thin conductors in HFWorks
Today’s tip is about thin conductors in HFWorks
High frequency devices usually involve very thin conductor such as the printed traces in PCB and IC circuits. Actually even if they are not geometrically very thin, they are usually electrically so because at high frequencies, the wavelength is very small. Such thin conductors are difficult to mesh and could lead to a very large number of mesh elements. Fortunately, SolidWorks has a neat feature called split surfaces which consist of splitting a surface to one or more sub-surfaces. Hence, we recommend to not represent the thin conductors with any part or body. Simply split the upper surface of the substrate and apply the corresponding boundary condition just on the metallic split sub-surfaces. This trick minimizes the number of mesh elements considerably and gives accurate results.
