Remcom has officially announced the integration of XFdtd® 3D Electromagnetic Simulation Software with Wireless InSite® 3D Wireless Propagation Software through a new Huygens surface capability.
According to certain reports, the stated development puts together dynamic mobility to facilitate the movement of RF systems, vehicles, and people through virtual wireless scenarios.
More on that would reveal how the overarching idea here is to allow seamless interoperability between high-resolution near-field simulations and efficient 3D ray-tracing, thus supporting applications such as GNSS, 6G connectivity, lunar missions, and on-body communication while in motion.
We must also touch upon how thanks to XFdtd’s full-wave simulation capabilities, RF engineers can seamlessly capture steady-state electric and magnetic field data for complex designs involving MCAD, ECAD, PCB, scatterers, and circuit matching networks.
Another detail worth a mention here is rooted in Remcom’s unique Huygens surface capability which, on its part, treads up a long distance to keep fidelity while incorporating these results into large-scale scenarios within indoor spaces, urban areas, or complex outdoor environments. You see, leveraging the given integration, users can transfer near-field complex electromagnetic field data from XFdtd to Wireless InSite via a simplified workflow.
This they can also do using precise ray-tracing to calculate propagation and multipath in large indoor and outdoor scenes with mobile devices, people, and vehicles.
“Remcom’s Huygens technology merges the worlds of full-wave and ray-tracing to bring accurate near-field results to challenging electrically large environments,” said Tarun Chawla, director of business development at Remcom. “As wireless devices proliferate on complex scatterers like the human body or vehicles, accurately modeling effects like blockage, dielectric refraction, and antenna detuning is crucial. These requirements are driven by RF testing, including anechoic chamber and OTA channel sounding, which need correlation with RF digital twins.”
Moving on, Wireless InSite also arrives on the scene bearing an ability to calculate communication metrics such as propagation paths, S-parameters, received power, SINR, and data throughput, while simultaneously maintaining the correct relative positions of geometry and antenna field data in dynamic scenarios. Here, the Huygens configuration can be placed anywhere in the scene and moved through time via mobility options that reveal how motion or moving objects and people affect fading and shadowing.
Taking a deeper view of some key applications supported by the given integration, they include GNSS positioning, where the solution allows for accurate modeling of handheld devices on walking humans in urban environments. This includes capturing multipath effects from 3D structures and signal losses from foliage, as observed from moving satellites.
The next application in line talks to NASA Artemis Program. In this context, Remcom can be expected to support future lunar missions with wireless channel simulation and coverage analysis for lunar environments, including simulation of MIMO antennas on spacesuits during moonwalks, digital elevation maps (DEM), and analysis of network performance impacts due to regolith dust, sub-surface scattering, and blockage from rovers and craters.
Then, there is an application concerned with 5G/6G Connectivity for UAVs, Automotive, and Robotics. Basically, when it comes to AI-native 6G networks, performance will be likely driven by ML algorithms that require training data. These algorithms, on their part, can be aided with Wireless InSite’s mobility and EES metamaterials features, as well as through accurate simulation of propagation and multipath in complex indoor, outdoor, terrestrial, satellite, and non-terrestrial environments.
Another detail worth a mention presents an application of on-body communications. This refers to on-body communication modeling for wearables, including smartphones, earbuds (TWS), smartwatches, UWB positioning tags, 5G UE sidelink, and smart rings. Such a mechanism, like you can guess, ensures RF engineers can analyze interactions between the human and the device to optimize wireless performance across wearable ecosystems.
“Remcom datasets are being used to digitize RF test and measurement using AI/ML models, capturing real-world wireless system user experience, from subcircuit to channel. We’re helping NASA achieve this for challenging Artemis missions by simplifying complex antenna analysis in dynamic scenarios. This integration between XFdtd and Wireless InSite is the first step toward a unified Remcom EM platform,” said Chawla.
