Remcom has introduced a new Huygens surface capability that incorporates near-field antenna effects into simulations of antenna performance. This allows for the analysis of mobility, multipath and interactions with body-worn devices in realistic environments. The Huygens surface capability is integrated with dynamic mobility, enabling the movement of RF systems, vehicles and people through virtual wireless scenarios. Seamless interoperability between high-resolution near-field simulations and efficient 3D ray tracing supports applications such as GNSS, 6G connectivity, lunar missions and on-body communication while in motion.

Steady-state electric and magnetic field data for complex designs involving MCAD, ECAD, PCB, scatterers and circuit matching networks can be transferred from Remcom’s XFdtd into Wireless InSite, where 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.

The update supports several important applications:

• GNSS positioning: Accurate modeling of handheld devices on walking humans in urban environments, capturing multipath effects from 3D structures and signal losses from foliage, as observed from moving satellites
• NASA Artemis Program: Wireless channel simulation and coverage analysis for lunar environments, including simulation of MIMO antennas on spacesuits during moonwalks, digital elevation maps and analysis of network performance impacts from regolith dust, sub-surface scattering and blockage from rovers and craters
• 5G/6G connectivity for UAVs, automotive and robotics: Wireless InSite’s mobility and accurate simulation of propagation and multipath provides training data to ML algorithms in AI-native 6G networks
• On-Body communications: Unique on-body communication modeling for wearables, including earbuds, smartwatches, UWB positioning tags, smart rings and more, allows RF engineers to analyze interactions between the human and the device and optimize wireless performance across wearable ecosystems.
