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.

CST STUDIO SUITE Simulations Replace Prototype Builds For Convergentia

CST STUDIO SUITE Simulations Replace Prototype Builds For Convergentia Document type
Portable devices such as smartphones and tablets nowadays contain many wireless systems, including cellular, Wi-Fi and GPS. Each system requires a functional antenna, since poor antenna performance may lead to a bad user experience in the form of low data throughput or poor coverage, and can cause calls to be dropped and car navigation to fail. On the other hand, devices must look appealing and their size must be minimized. The thinness of the devices and the presence of metallic structures have caused challenges to antenna design. Without 3D simulations, there is a high risk of having poor antenna performance or clumsy industrial design. The alternative for antenna verifi cation is to use multiple prototyping rounds, which are expensive and have a long lead time. However, there are things that cannot be effectively studied with prototypes, for example grounding structures and impedance matching networks. Read full article..

Designing Building Structures for Protection against EMP and Lightning

Designing Building Structures for Protection against EMP and Lightning
We will explore the application of CST STUDIO SUITE® to the simulation of EMP and lightning effects. Simulation will be used to analyze the shielding effectiveness of a building structure, evaluate the impact of adding personnel entryways and utility pipes and predict the transient currents induced in cable systems. The performance of EMP protection measures at the point of entry, such as filtering and clamping, will be assessed. We will simulate a lightning strike to a building structure and visualize the induced current return paths. A lightning protection system (LPS) will be analyzed including the effect of down-conductor type and grounding impedance. Different positions of cable systems inside the building will be simulated and the induced shield and internal load currents predicted. Read full article..

Designing Clean Mobile Electronic Devices – Mobile Phone & Automobile Systems

Designing Clean Mobile Electronic Devices – Mobile Phone & Automobile Systems
Mobile electronic devices have become both more numerous and more compact while at the same time integrating more and more radio frequency (RF) functionality. Multiple transmit and receive systems with different communications protocols and with different antennas are routinely being used for personal communications: voice, data, location services, etc. High speed clock and data lines in devices can radiate and couple to antennas. Modern automobiles can have 10 to 30 antennas at different frequencies and locations for functions ranging from collision avoidance to tire pressure. To make introduction of new products in this environment faster, it is important that the possible couplings between the various systems on one platform can be determined before fabrication and field testing. We will discuss the use of CST STUDIO SUITE to perform EM analysis of a cell phone with multiple antennas and high speed data lines, and of an automobile containing an LTE cell phone, commercial FM, GPS, and commercial VHF & UHF antennas.

Power Delivery Network PDN Analysis

Power Delivery Network PDN Analysis
This webinar consists of two parts. The first part will highlight the role of simulation in the design of PCB power delivery network (PDN) systems, including the voltage regulator module (VRM), decoupling capacitors (decap), and the spreading parasitic of the power/ground plane. The PDN analysis will focus on both the static case (voltage or IR-Drop) and AC analysis in the frequency domain, with the main focus on PDN impedance. In addition to the AC analysis, we will also demonstrate the decap optimizing tool, which is mainly used to optimize the number of decaps while reaching the target impedance. A brief explanation about the SSO (simultaneously switching output) and the major challenges for simulating this (SI/PI co-simulation) will close the first part of this webinar. The second part of the webinar will cover the measurement methodology for the PDN impedance of the power supply plane of the PCB. This will include the measurement the PDN impedance from only one side of the PCB without the connector. Read full article..
