On-body Propagation

Innovative full-wave near-field domain and ray-tracing far-field domain have been combined to solve challenging on-body propagation test and measurement. XFdtd 3D EM Simulation Software captures the performance of antennas and interactions with people, vehicles, and structures in the near-field of the antenna with high fidelity. This domain is transferred to Wireless InSite 3D Wireless Prediction Software, which supports refraction into volumetric materials and further refines the simulation of complex electromagnetic interactions with the body or nearby structures for technologies such as 6G, GNSS, WLAN, lunar missions, and on-body communication while in motion.

Lunar Astronaut and Surface Communications

NASA, ESA and JAXA are trusting high fidelity ray-based techniques to develop wireless communications networks on the moon. To support NASA’s Artemis mission, Wireless InSite ensures accurate simulation of RF propagation on the Moon by providing the ability to import LRO LOLA terrain datasets and accurately transform the coordinates of RF mobile systems upon the lunar terrain, while also incorporating a lunar materials database. These features are essential for planning lunar missions by capturing the reflection and refraction characteristics inherent to lunar terrain.

Load Pull Analysis in XFdtd EM Simulation Software
Wednesday, June 18, 2025 at 4:00 p.m.

One aspect in maximizing the performance of communication systems concerns optimizing the performance of the Power Amplifier (PA) in the Radio Frequency (RF) front end. Load pull is a fundamental characterization method that allows RF engineers to push the performance boundaries of RF systems by understanding and manipulating the complex impedance a power amplifier sees looking into a matching network and antenna system across multiple frequencies. 

Load pull requires precise impedance matching to maximize output power and efficiency to help the RF community meet the demands of high-performance RF applications such as 5G networks, satellite communications, and advanced wireless technologies. 

By utilizing Remcom’s FDTD solver and schematic editor, engineers can analyze frequency-dependent load pull data to optimize critical performance parameters like total radiated power. This approach is particularly crucial in modern radio communication systems, especially 5G, where reducing power consumption and improving system performance are paramount.

RF Digital Twins with Human Bodies: A Hybrid EM Simulation Approach
Wednesday, June 18, 2025 at 4:30 p.m.

Achieving reliable wireless connectivity on and around the human body presents significant challenges due to radiation hazards, coupling, antenna design complexities, and OTA measurement requirements. RF simulation that models electromagnetic effects plays a critical role in addressing these issues. This work demonstrates the use of the full-wave finite-difference time-domain (FDTD) method to create near-field Huygens boxes that incorporate MCAD models, PCB designs with circuit-level details, and surface mesh of a human body. For electrically larger environments, these near-field Huygens boxes are integrated into 3D ray-tracing simulations to evaluate in situ environmental effects, including human presence for blockage. The hybrid approach is correlated, accounts for multipath effects for GNSS and indoor, and delivers significant runtime savings, providing a comprehensive RF digital twin solution for RF test and measurement.

Determining the final set of component values in a matching network can be a challenging process. At higher frequencies, especially VHF and above, significant EM effects on the real circuit (inter-connection transmission line effects and coupling between the antenna being tuned, other antennas, and other parts of the structure) are difficult to quantify and account for in circuit schematic simulators alone.
