  • Why create a MyCST Account ?

    A MyCST account may facilitate your access to many of the offerings on the CST website, for example the registration for eSeminars and the watching of eSeminars recordings, setting email preferences, and there is more functionality to come. It is required to participate in workshops and trainings.

  • Personal PreferencesAllows you to update your email preferences and areas of interest. It helps us to personalize your experience.

  • EventsSearch for events by location, industry and application. Once you are registered, you will be able to manage your registrations and check important details about your events. This section also provides you with a repository for Workshop & Training material.

  • LibraryYou can collect articles you find on the CST website to reference or read later by clicking on the “Add this article” button at the bottom of the article page.

  • Create Your Own Account
  • Need technical Support ?

    Customers can customize their accounts once they have completed the account creation process. This platform acts as vivid interface between CST and our customers.

    We therefore offer access to the latest Service Packs (including an automatic notification that a new Service Pack is available), a steadily growing database of Frequently Asked Questions (FAQs), Application Notes and Training Videos, as well as an individual FTP section for easy exchange of large files with our support team.

  • Do I need an Account?To access the Support Site a valid maintenance contract and a one-time registration is required.

    Please note that your Support login does not work for the MyCST account.

CST – Computer Simulation Technology

SPARK3D

SPARK3D is a unique simulation tool for determining the RF breakdown power level in a wide variety of passive devices, including those based on cavities, waveguides, microstrip and antennas. Field results from CST Studio Suite® simulations can be imported directly into Spark3D to analyze vacuum breakdown (multipactor) and gas discharge. From this, Spark3D calculates the maximum power that the device can handle without causing discharge effects.

Typical approximate approaches to determine the RF breakdown power level of any component are intentionally extremely conservative. Spark3D is based on advanced methods which analyze the breakdown phenomena numerically, predicting more realistic breakdown power levels, and thus improving the design margins.

The main Spark3D features are:

-           Import the electromagnetic (EM) fields from different EM solvers.

-           Automatic determination of the breakdown power threshold.

-           Analysis boxes can be defined in order to choose the critical regions to be analyzed.

-           Real-time output interface with rich simulation data, in table, plot and 3D view forms.

SPARK3D is an optional part of CST Studio Suite® and is also available as a stand-alone offering.

 

Multipactor

The multipactor effect is a microwave breakdown discharge occurring in vacuum conditions caused by the formation of an electron avalanche. The avalanche originates due to the release of secondary electrons when high energy electrons collide with the walls of the device. This results in the appearance of an electron plasma which degrades the response of the component.

With Spark3D you can perform full numerical simulations of the multipactor effect considering the 3D EM field distribution. This is done by launching electrons in the component, tracking their trajectories and checking the evolution of the electron number with time. 

 

Gas discharge (also known as corona discharge or ionization breakdown) is a breakdown discharge occurring in gas-filled components caused by the formation of an electron avalanche. The avalanche originates due to the ionization of the gas molecules when electrons impact to them. This results in the appearance of an electron plasma which degrades the response of the component which can, eventually, destroy it.

With Spark3D you can perform full numerical simulations of the corona effect considering the 3D EM field distribution. This is done by solving the free electron continuity equation in the component and checking if this density would grow with time for a particular input power level.
