CST market overview

CST offers products suitable for a wide range of electromagnetic design tasks, capable of simulating numerous components and systems.

Together, the products in the CST STUDIO SUITE® family can carry out electro- and magnetostatic, stationary, low-frequency and high-frequency simulations, as well as being able to calculate the effects of EM fields on substances as diverse as magnetic materials, biological tissues and charged particles. Tight integration with third party tools extends the application range even further.

The applications of CST software are almost limitless; among the devices that CST products have been used to simulate are couplers, filters, connectors, antennas, inductors, capacitors, PCBs, waveguides, travelling wave tubes, optical devices, sensors, actuators, electrical machines, SAR, MRI coils and cable harnesses, to name but a few.

Worked examples of applications of CST software are being added all the time. These can be found sorted by application area in the menu on the left, or through the site search at the top of each page.

"Leaky" Cables Make Fine Broadband Antennas

"Leaky" Cables Make Fine Broadband Antennas
A cable that leaks electromagnetic energy sounds like a defective cable. Yet, ironically, it makes an excellent broadband antenna. To avoid confusion, antennas based on this approach are called leaky feeders. They are typically used in environments that mirror the cylindrical shape and length of the cable: tunnels, mines, aircraft, railroad tracks and skyscrapers. CST provides a tutorial explaining the basic theory and electromagnetic performance. Turning theory into practice, with assistance from W. L. Gore, we examine their use enabling Wi-Fi and cellular service on commercial airlines and corporate jets. Read full article..

Lead Frame Package Layout and EM Simulation using CAD Design Software and CST STUDIO SUITE

Lead Frame Package Layout and EM Simulation using CAD Design Software and CST STUDIO SUITE Document type
Lead frame packages are an established packaging technology for many types of applications, due to their manufacturing and cost advantages. When the limits of this technology are pushed, careful analysis of these packages using state-of-the-art design and simulation tools becomes essential. This technical white paper describes a workfl ow of rapid design and simulation for lead frame packages using CAD Design Software’s (CDS) Electronics Packing Designer (EPD) software, and CST STUDIO SUITE®.

RF Breakdown Analysis in Space Applications

RF Breakdown Analysis in Space Applications Document type
Devices in the output section of a satellite payload, including filters and multiplexers are subject to high RF power. This could lead to RF breakdown, which may render the specific device useless and, in the end, degrades the reliability of the satellite. Therefore all space high power devices have to be analyzed with regards to their breakdown behavior. This application note shows how CST STUDIO SUITE® and SPARK3D® can be used to investigate these effects via simulation. Read full article..

USB 3.1 Type-C Simulation and Compliance Test

USB 3.1 Type-C Simulation and Compliance Test
USB 3.1 Type-C Connector Simulation and SI compliance tool. With the continued adoption of USB interface, there is a need to adapt the USB technology with the newer devices as they become smaller, thinner, lighter and faster. Several types of USB connector are currently available on the markets, including the Type-A, Type-B, Mini-A, Mini-B, Micro-A and Micro-B. All of these different types of USB connector are by design difficult to insert incorrectly when mating the USB plug and receptacle. Read full article..

Designing a Phased Array Antenna Using Antenna Magus and CST STUDIO SUITE

Designing a Phased Array Antenna Using Antenna Magus and CST STUDIO SUITE Document type
Antenna synthesis lets engineers investigate many potential designs and produce antennas that fit the specifications quickly. For effects that cannot be accounted for analytically such as edge effects and mutual coupling, full-wave 3D simulation can complement synthesis tools and allow designs to be checked and fine tuned. This article explores the synthesis of an antenna array, using a phased array satellite communications antenna as an example. Read full article..

Synthesis and Simulation Converge in CST STUDIO SUITE 2015

Synthesis and Simulation Converge in CST STUDIO SUITE 2015
Simulation helps engineers analyze and optimize products, while synthesis software helps them select and create designs. Alone, these are powerful tools for the development of any electromagnetic device. Combined, they complement and strengthen each other. With the release of the CST STUDIO SUITE® 2015, synthesis, design and optimization are now more tightly integrated into the simulation workflow. Read full article..

EMC Simulation in the Design Flow of Modern Electronics

EMC Simulation in the Design Flow of Modern Electronics
EMC compliance is a necessary condition for releasing products to market. National and international standards bodies such as the IEC2 and the FCC3 define limits on the emissions a device is allowed to produce, and automotive and aerospace manufacturers can set even stricter standards for their OEM suppliers. If these standards are not met, the product cannot be sold. Read full article..

State-Space modeling and simulation of a saturated core fault current limiter

State-Space modeling and simulation of a saturated core fault current limiter
This article demonstrates the ability in CST EM STUDIO® to simulate a fault current limiter. Two methods are shown, one based on a direct transient simulation at EM solver level, the other on the generation of a non-linear equivalent circuit from FE magnetostatic simulation results. The equivalent circuit, ECE, in this case is exported for use in Synopsys® Saber. In both simulations, the assumption has been made that the core is laminated and, as a result, eddy currents are suppressed. Such equivalent circuits are straightfoward to generate and are extremely efficient for use in circuit- and system-Level simulation. In large and complex power systems, a number of ECEs of system components such as transformers, generators and current limiters. Read full article..
