In recent years, more specifically in the months, I have received a large number of articles to review that rely on finite element method (FEM) or analysis (FEA) study different matters related orthodontics. Some these are excellent works, but vast majority very low quality and present neither proper justification for using FEA nor correct execution. Thus, write this editorial give some insight...

Several types of microfabricated mechanical filters are analyzed for RF communications applications and their advantages over the traditional SAW or FBAR filters are described. GHz frequency operation requires sub-micron dimensions. This work focuses on the modeling of a filter with torsional mode vibration. Ansys finite element simulation has been performed to make comparison with the analytic...
