Remcom supports five major product lines—XFdtd, Wireless InSite, XGtd, VariPose, and Rotman Lens Designer (RLD). XFdtd, the flagship of the Remcom product line, is full-wave 3D EM analysis software for modeling and optimizing device design based on the finite difference time domain (FDTD) method. XFdtd applications include antenna design, microwave circuits, scattering calculations, electromagnetic compatibility, photonic devices, and biological effects of electromagnetic fields. With these capabilities, Remcom has established a large customer base in multiple industry sectors and academic research industries.
In the Automotive Radar and Communication sector, Remcom’s products are used to simulate and analyze complete vehicles and multi-vehicle problems at millimeter wave frequencies, which assist automotive radar and vehicle-to-vehicle communication development. For Biomedical Electromagnetics, the company’s products provide the ability to simulate and analyze electromagnetic radiation in and around biological tissue, providing answers for MRI design, implantable medical devices and surface worn devices to better study the electromagnetic effects on the human body. Remcom’s antenna design capabilities have particularly influenced configuration for communications devices such as mobile phones, tablets, and notebook computers to optimize efficiency, far-zone coverage, and human tissue (SAR) exposure to users.
Remcom’s clients include IBM, Ericsson, Samsung, Sony Texas Instruments, General Motors, Mitsubishi, and all branches of the United States military. KEC, one of Remcom’s clients that designs and manufactures EMC interconnect components and cable harness assemblies, was looking to strengthen its market leadership and differentiate itself from the competition by offering a unique technology. Because a failed component is so expensive KEC uses XFdtd to model and simulate their customers’ designs and identify problems early in the process. They can then recommend corrections before the EMC certification stage enabling their customers to avoid costly mistakes and pass certification testing on the first try. Simon Ireland, design and development engineer at KEC, says, “We chose XFdtd because the product is so easy to use. Its interface is intuitive, making it simple to set up complex problems. Remcom’s solution was head and shoulders above the others we evaluated.”
Remcom’s expertise in EM simulation technology and its familiarity with customer issues enable them to provide relevant assistance to customers. “As EM specialists, we have an edge over other providers that are very large and diversified. Our focus allows us to provide very targeted solutions and service. In addition, we have stayed ahead of the curve with acceleration solutions for EM simulation. We were one of the earliest innovators to accelerate calculations using graphics processing units (GPU cards) in 2008 and Message Passing Interface (MPI) for GPU clusters in 2013, and we remain the leader in quickly simulating complex, very large problems,” said Langdon.
The future looks bright for Remcom as it continues to provide customers with advanced scientific software that not only supports standard computers but can also take advantage of the rapidly-evolving HPC hardware market where needed. “We will retain expertise in our core electromagnetic niche while continuing to expand into related computational markets,”concludes Langdon.
Remcom Announces XFdtd Electromagnetic Simulation Software Update with Advancements for Millimeter Wave Antenna Design
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, XFdtds 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.
