Remcom XGtd is a ray-based electromagnetic analysis tool for assessing the effects of a vehicle or vessel on antenna radiation, predicting coupling between antennas, and predicting radar cross section (RCS). It is ideally suited for applications with higher frequencies or very large platforms where the requirements of a full physics method may exceed available computational resources.

XGtd Ray-based EM Analysis Software Features
XGtd’s capabilities extend well beyond standard ray tracing codes, incorporating techniques including Geometric Optics (GO), the Uniform Theory of Diffraction (UTD), Physical Optics (PO), and the Method of Equivalent Currents (MEC). XGtd provides high-fidelity outputs tailored to its intended applications.
Computational methods include:
- Ray tracing methods: Shooting and bouncing ray and image theory
- E-field evaluations using UTD, GO, PO, and MEC
- High-fidelity field predictions in shadow zones including creeping wave effects
- Multipath calculations including reflections, transmissions, wedge diffractions, surface diffractions, and creeping waves
