Welcome to CST MICROSTRIPES, a powerful and easy to use 3D electromagnetic modelling tool for fast and accurate simulation of high frequency electromagnetic problems. The tool is a complete package that allows an engineer to efficiently design and analyse electromagnetic devices and structures. |
CST MICROSTRIPES is a software tool for 3D electromagnetic analysis and design of devices and structures that operate in the high frequency range.
The design process follows five easy steps:
- Define the geometry using a versatile and intuitive solid modeller based on the ACIS kernel, or import the geometric model from another CAD package
- Assign the material properties to the geometry
- Choose your type of excitation (e.g. port or plane wave)
- Define the results you wish to obtain (radiation patterns, VSWR etc.)
- Then let the efficient time domain solver based on the TLM (Transmission Line Matrix) method provide you with accurate broadband results.
On completion the solution results will be automatically displayed. Further 3D visualisation is offered via the Field Plotter which allows you to view E and H field components, surface currents, power densities and SAR over the solution volume to gain an insight of the behaviour of the device.
- Fast, efficient, accurate and stable time domain solver based on the TLM method
- Parallel solver taking advantage of multi-processor hardware platforms
- Full broadband response achieved after a single run
- Uses the familiar Windows user interface
- Advanced ACIS based parametric solid modelling tool

- Import of 2D CAD data through DXF (AutoCAD)
- Export of 3D CAD data through SAT, STEP, IGES and STL file format
- Multigrid mesh capability
- Compact models for wires, slots, vents and thin panels allow small features to be efficiently and accurately modelled within a coarse mesh
- Calculation of field distributions (Electric, Magnetic fields, surface currents, power flows, power densities, power loss densities and SAR) at user specified frequencies
- Isotropic and anisotropic material properties
- Frequency dependant material properties (permittivity and permeability) as defined by the Debye and Lorentz representation
- Broadband S parameters calculated after a single run.
- Calculation of loss integrals for each geometry entity for Q and Gain calculations
- Surface impedance model to account for loss in conductors
- Model excitation through Ports (Waveguide rectangular TE, Circular TE/TM, microstrip, stripline, coaxial, co-planar and other)

The help topics for CST MICROSTRIPES are split into the following sections.
Getting Started
This secion describes how to use the CST MICROSTRIPES window, from which all the tools of the product are accessed.
Build
Build is the 3D solid modelling tool which is used to create the geometry or import it from other CAD tools. Most industry standard CAD formats can be imported. Within Build the electromagnetic parameters needed for the model and results required are defined.
Plot Results
A number of plotters are available for display of graphical results, 3D results, and near and far field results.
Modelling Issues
The modelling concepts of CST MICROSTRIPES are discussed.
Utilities
A set of utilities are available to post-process results for non-standard outputs.
