Scalable Modeling of Human Blockage at Millimeter-Wave: A Comparative Analysis of Knife-Edge Diffraction, the Uniform Theory of Diffraction, and Physical Optics Against 60 GHz Channel Measurements
Human blockage at millimeter-wave frequencies is most commonly modeled through Knife-Edge Diffraction (KED) from the edges of the body shaped as a vertical strip. Although extensively validated in controlled laboratory experiments, the model does not scale to realistic 3D scenarios with many, randomly oriented bodies, on which multipath signals can be incident from any direction, not just normal to the strip. To address this, in this article we investigate computational electromagnetic methods based on raytracing.
Optimization of 5G Infrastructure Deployment Through Machine Learning
Assessing 5G Radar Altimeter Interference for Realistic Instrument Landing System Approaches
The safe rollout of new or enhanced 5G services using C-band spectrum near airports in 2022-2023 will require realistic modeling of radio propagation to mitigate potential interference with legacy radar altimeters which remain in operation as of summer 2022. In this whitepaper, we use Wireless InSite to provide a realistic assessment of radar altimeter interference due to emissions from 5G base stations along a landing approach to runway 27L of Chicago O’Hare International Airport.

Mitigating Wave Scattering – Challenges Facing 5G Wireless Signal Propagation
The following article appeared in the Spring 2020 issue of Focus on Materials, a quarterly bulletin produced by the Pennsylvania State University's Materials Research Institute. Professor Ram Narayanan of Penn State's College of Engineering worked with Remcom to produce a 5G millimeter wave coverage concept using existing AT&T towers in State College, PA, showing ray path predictions generated in Wireless InSite. Here Professor Narayanan discusses the challenges facing 5G signal propagation.

Computation of Fields and SAR for MRI with FDTD Simulation
The simulation procedure allows the coil designer to get quick feedback on the performance of the device, without the time or cost of producing numerous prototypes. The further ability to simulate the structure in practical use, such as the coil around a body part, permits the designer to optimize the device under loaded conditions and ensure that the regulated limits such as SAR are within thresholds. In this article, a SAR analysis for an MRI system is presented using XFdtd.
