Applications

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.

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..

Traveling Wave Tube Design with Simulation

Traveling Wave Tube Design with Simulation
The development of electron devices or vacuum tubes has advanced a lot over the last century. The principle behind a traveling wave tube (TWT) is the interaction between an electron beam and an electromagnetic wave in a slow wave structure (SWS), by which an input RF-signal is amplified converting the energy of the electron beam into a powerful electromagnetic wave. This webinar will show how the design of such tubes can be bolstered by the use of simulation tools and high-performance computing, beginning with adjusting the geometry of the SWS such that beam and phase velocity of the wave are synchronized. Only one pitch of the SWS needs to be simulated and optimized, using a particle-free eigenmode solver. Further, the analysis of couplers will be shown in terms of their transition behavior. The webinar will conclude with the simulation of a hot test, including the particle beam, to predict the amplification behavior and output frequency. Throughout, simulation speeds and the performance benefits of GPU computing will also be explained. Read full article..

MIMO Antenna Systems for Advanced Communication

MIMO Antenna Systems for Advanced Communication
Multiple-input, multiple-output (MIMO) systems are a major field of study for researchers interested in achieving high data rate communication in typical urban multi-path environments. Although a fast analysis can be based on S-parameters, this approach has limitations. A more detailed analysis needs to take into account broadband, farfield and antenna properties. These are especially important in presence of the human body. This webinar will show how simulation can be used to calculate the effect of hand and head (e.g. CTIA models) on mobile devices, MIMO for wearable antennas and different power weighting functions for different environments, along with post-processing options for envelope correlation (including spatial power weighting functions), derived quantities diversity gain and multiplexing efficiency. Finally, there will be a demonstration of the link between CST MICROWAVE STUDIO® and Optenni Lab for multiple antenna matching to optimize power transfer to antennas while minimizing cross-coupling.

Electromagnetic Simulation Applied to Automotive EMC Testing

Electromagnetic Simulation Applied to Automotive EMC Testing
Nearly every product that has some sort of electronic circuitry must be subjected to EMC testing prior to its commercialization. In the automotive industry, the large number of electronic modules, sensors, and cable harnesses, many in safety-critical systems, in modern vehicles demands strict standards for reliability and security under challenging conditions. Vehicles must comply with standards such as CISPR-25 and ISO 11451, and individual regulations from the automakers which, very often, are even more stringent. Read full article..

EMC Simulation in the Design Flow of Modern Electronics

EMC Simulation in the Design Flow of Modern Electronics
In the design process of modern electronics, every product development starts with a schematic and ends with the physical implementation of the device, typically done in copper. Along the way to converting the schematic into a real existing layout however, the designer can fall into numerous possible pitfalls in terms of the EMC performance. In this webinar we will show several examples of EMC countermeasures in modern electronics and good practices for implementing them, as well as highlighting some common mistakes. We will also demonstrate how simulation can predict the EMC performance of typical components like PCBs, enclosures and cables, and compare the simulation results to measurements performed on physical implementations of the structures.
