Design engineers considering the use of microelectromechanical systems (MEMS) devices can perform some free analysis, thanks to a 30-day trial offer for electromagnetic (EM) simulation software from Coventor (Cary, NC). The company's EM3DS three-dimensional EM solver software provides a customizable way for designers to calculate electromagnetic effects on MEMS devices. The simulation tools are complementary to CoventorWare(r), Coventor's existing suite of software tools for RF, microware and/or MEMS devices or may be used as a stand-alone product. The EM3DS tool uses a method-of-moments (MoM) platform as opposed to typical FEM based simulations. MoM is ideal for structures involving high aspect ratios.

The software features pre- and post-processing capabilities, linear circuit analysis, network parameters, Smith charts, S-parameters and SPICE extractions. An object oriented integrated editor enables calculations by means of expression and frequency-defined materials. Geometry information may be imported from GDSII, AutoCAD DXF and BMP files.
