CST and Rohde & Schwarz team up for the “Measurement meets Simulation” workshop

Simulation and measurement are complementary tools, and together they offer more than either technique can alone. However, this is only true when the results of the two are comparable.

There are various reasons why simulation and measurement may not agree, even when it seems like you’ve done everything right. These include the simulation set-up, manufacturing variations in the prototype, and the effect of connectors and cables used in the measurement. Therefore CST has teamed up with Rohde & Schwarz, the world’s leading manufacturer of wireless communications and EMC test and measurement equipment, to put together a workshop titled “Measurement meets Simulation” The aim of this workshop is to give engineers an insight into how to achieve accurate simulations and show best practice guidelines to getting better measurements.

The first workshop was held at Loughborough Antennas and Propagation Conference (LAPC) 2013 and attracted 40 participants, from both industry and academia. Participants learned how to design and simulate a patch antenna using CST STUDIO SUITE®, and how to measure its performance using the new ZNB and ZNC network analyzers from Rohde & Schwarz. In addition, they also learned about how under- and over-etching can affect the performance of prototypes, and how to estimate the effect of manufacturing tolerances using sensitivity analysis.

With the success of the first workshop, CST and Rohde & Schwarz are now bringing the workshop to other locations. The next workshop will be held in Dublin, Ireland on 9 July, 2014. If you are interested in attending, the agenda and registration details can be found on our website.

Trends from the CST European User Conference 2014

This year’s European User Conference helped to show us just how users are implementing electromagnetic (EM) simulation into their design workflows. The event, including workshops and a two-day conference, was held in Berlin from May 7-9 and gathered users from diverse industries to facilitate knowledge exchange through various application-based technical presentations. Even during the coffee and lunch breaks, insights on engineering design challenges and solutions were being shared between users.

We covered topics in a range of application areas. Although antennas remained a popular session, we saw an increasing amount of interest in EMC and also introduced new sessions on high power microwaves, high performance computing, components and optical applications. With the diversity in applications continuing to grow, the conference is incredibly useful in seeing how CST software is being used to address today’s complex engineering challenges in industries ranging from phones to particle accelerators, and from railways to radio-astronomy.

Our keynote speakers brought with them expertise from the cutting-edge of industry. Prof. Wolfgang Heinrich shared his knowledge of extremely high frequency integrated circuits operating in the 100 GHz regime, while Dr. Bruce Archambeault both spoke about the role of simulation for EMC/EMI analysis on PCBs and led a workshop on EMC simulation.
Now with this year’s event over, we are already planning for CST EUC 2015 to be held in Darmstadt, Germany from April 28-29. Keep a look out for more news as we get closer to the date.

As always, some of the technical presentations from CST EUC 2014 are available to download with the permission of their authors.
