Remcom Announces XFdtd Electromagnetic Simulation Software Update


Reading time ( words)

Remcom announces an update to XFdtd® 3D EM Simulation Software, with new features to address 5G millimeter wave antenna design challenges including support for high-performance tuners and singularity correction. In addition, PCB import enhancements save time in the design workflow.

As mobile devices continue to grow in complexity, engineers are challenged to include more antennas in less available space within the device while maximizing efficiency.  Multi-port RF devices such as tuners and switches can be utilized to optimize band coverage.  To accommodate these innovations, XFdtd's Circuit Element Optimizer (CEO) now includes multi-port device functionality, enabling engineers to incorporate and test these components in their matching network simulations.

Singularity correction is a sophisticated meshing method that accurately captures highly varying electromagnetic fields around the conductive edges of geometries such as antennas or transmission lines.  XFdtd adjusts the electric and magnetic field values adjacent to metallic edges during time stepping.  For higher frequency and millimeter wave use cases, where numerous antennas and components create high spatial variation of fields, singularity correction can significantly improve accuracy and strengthen confidence in the expected behavior of a device.

The new XFdtd release also includes enhancements to printed circuit board (PCB) import, allowing documentation layers of a PCB to be imported alongside the geometry.  These layers typically include useful manufacturer information such as the build date of the device, ID number, and more.  Lastly, lumped circuit components specified in ODB++ and BRD files are also imported, eliminating the need to manually add them afterwards.

Physics, Electrical Engineering, and PCB Design

12/20/2022 | Tamara Jovanovic, Happiest Baby
When I was a sophomore in college, I had an amazing professor for Physics II: Electricity and Magnetism. He made a series of complex topics fun to learn, and his personality and way of teaching were almost tailor-made for the way I like to learn. He explained new concepts through practical examples, and always kept students engaged throughout the class, making sure everyone understood the lectures. Physics II was an engineering prerequisite, and I didn’t mind taking the class since I really enjoyed the material. However, I did find myself wondering a few times, “Will I ever use any physics in real life?” It turns out that the answer to the question was yes.

Sunstone’s Matt Stevenson Shares Insights From New PCB Design Book

10/27/2022 | Nolan Johnson, I-Connect007
There’s designing the “perfect” circuit board and then there’s designing a board that is “perfect for manufacturing.” While seasoned designers and design engineers understand many of the nuances, PCB fabricator Sunstone Circuits has just published a new book specifically for new designers who have the knowledge of design but are still learning what it means to get the board manufactured. Sunstone’s Matt Stevenson takes the reader through a series of situations that should help clarify what’s happening in the fabrication process and how to adjust a board design to be better suited for manufacturing.

Sunstone and I-007eBooks Launch Book on Designing for Reality
