Plasma trails created by hypersonic vehicles passing through the atmosphere create challenges for radar detection and radio communication through the plasma layer. This paper discusses the FDTD method to simulate the behavior of plasma materials using Remcom’s XFdtd 3D EM Simulation solver and presents validation in one and three dimensions.

Engineered electromagnetic surfaces (EES) are passive metasurfaces designed to artificially enhance wireless signal coverage. In this paper, propagation experiments are conducted to verify the accuracy of a novel ray-optical scattering model for EES. Wireless InSite’s implementation of the scattering model is presented along with measured and simulated propagation data for a large indoor office environment.

TVS diodes help protect electronic circuits from surge voltages associated with an ESD event. This paper demonstrates XFdtd’s transient EM/circuit co-simulation capability, an approach that embeds a transient nonlinear circuit solver in the full-wave simulation so that all electromagnetic phenomena are accounted for in a single time-domain simulation.

In 5G and 6G, mmWaves bring the promise of new, high bandwidth frequency bands. Propagation losses and fast fading due to increasingly mobile devices and short wavelengths pose challenges for these new concepts. This paper explores the effectiveness of massive MIMO beamforming at mitigating mmWave propagation challenges using Wireless InSite and its mmWave hybrid beamformer capabilities to transmit data streams to a sedan driving in central Manhattan.

Wireless InSite supports the simulation of RF interactions with engineered electromagnetic surfaces (EES). This allows modeling of passive metasurfaces designed to optimize wireless communication coverage by manipulating how signals propagate through a scene. This paper demonstrates how Wireless InSite simulates and analyzes the channel characteristics of EES in any environment, including indoor, outdoor, outdoor to indoor, and others.

The safe rollout of new 5G services using C-band spectrum near airports requires realistic modeling of radio propagation to mitigate potential interference with legacy radar altimeters. In this whitepaper, Wireless InSite provides a realistic assessment of radar altimeter interference due to emissions from 5G base stations along a landing approach.
