Functionality

CAD Model Construction

CST MICROSTRIPES™ model builder utilizes the ACIS modeling kernel for fast and easy creation of solid geometry. Boolean operations, library parts, sweeps and transformations are all available. Spirals, parabolas and many other shapes can be defined by parametric equations.

CAD Import

Objects defined in IGES, STEP, STL and DXF formats may be reliably imported/exported, "healed" and subjected to editing. While the ACIS native file format SAT can be easily imported and exported without requiring any additional effort.

Intuitive Interface

The CST MICROSTRIPES™ GUI has been developed utilising the Microsoft MFC interface allowing users to configure the interface display windows, toolbars and dialog boxes to meet their personal preferences.

Advanced Usability

Absorbing Boundaries (PMLs)

The extent of free space surrounding an antenna can be reduced by applying PML boundary conditions, allowing for a faster analysis of the problem.

Wrap-Around Boundaries

In addition to symmetry boundaries, wraparound boundaries are available for simulating periodic structures such as frequency selective surfaces (FSS) or periodic arrays.

Slots and Seams

CST MICROSTRIPES™ has the ability to model thin slots and seams without the need to locally refine the mesh - leading to more efficient simulations while maintaining the accuracy of the solution.

Vents & Windows

The penetration of EM fields through (below-cutoff) perforated metal screens can be simulated, even when the individual perforations are smaller than the cell size.

Frequency-Dependent Materials

Multi-pole Debye and Lorentz representation of frequency-dependent dielectric and permeable materials are available within the software library, with the ability to quickly and easily add new materials.

Conductive Films

The frequency-dependent "diffusion" of EM fields through conducting films and panels is accurately represented - even when the skin-depth is much smaller than the computational cell size.

Wires and Wire Bundles

CST MICROSTRIPES™ can model wires finer than the computational cell size. Wire currents are fully coupled to the EM field, with conservation of energy and flux. Up to 50 individual wires can pass through a single cell.

Lumped Component Networks

CST MICROSTRIPES™ sub-cell wires may be terminated by linear networks. Each network can connect to other wires and/or be grounded on a metal body.

Excitations

Within CST MICROSTRIPES™ models can be excited in a variety of different ways such as by ports and plane waves. Ports, which can be waveguide, coaxial, microstrip, stripline, co-planar, slotline or wire source can be specified anywhere within the workspace and do not have to be coincident with the boundaries. It is also possible to activate multiple ports in a simulation to operate either sequentially or simultaneously, with or without phase delay. The excitation is an impulse in the time domain and the resulting output (impulse response) can then be convolved with user definable waveforms giving results as if the model had been excited with said waveform.

SAR

Spot SAR

CST MICROSTRIPES™ can calculate the specific absorption rate (SAR) field (W/kg) in any lossy medium. One time-domain simulation can provide the SAR field at many frequencies.

1g and 10g Averaged SAR

The SAR averaged over the nearest 1 and 10 grams of tissue is also provided at each frequency.

Biological Tissue Library

Over 40 biological tissue types: aorta, bladder, blood,uterus are included as 4-pole Debye frequency dependent models.

SAM Head

A model of the standard Specific Anthropomorphic Mannequin (SAM) phantom test head is available.

Installed Performance

SAM's effect on the radiation pattern and radiation efficiency can be determined from the same simulation.
