XGtdReleaseFar Zone Radiation, RCS, and EMI/EMC for Electrically-Large Platforms

XGtd is a general purpose ray-based electromagnetic analysis tool for assessing the effects of a vehicle or vessel on antenna radiation, estimating radar cross-section (RCS), and predicting coupling between antennas.

Based on Geometric Optics and the Uniform Geometrical Theory of Diffraction (GTD/UTD), performance and memory requirements are not affected by the physical size of objects, but rather by the number of faceted surfaces used to model them. This makes it ideally suited to applications with higher frequencies or very large platforms where the electrical size of a computation may be too large for full physics techniques, such as Finite Difference Time Domain (FDTD).

XGtd also includes a number of capabilities that extend well beyond standard ray-tracing codes to provide high-fidelity outputs that are tailored to its intended application, including the following:


• Far Zone Antenna Radiation for surface-mounted antennas
• Monostatic or bistatic Radar Cross Section (RCS)
• Creeping Wave Diffraction: high-fidelity field prediction in shadow zones
• Doppler for moving transmitters and receivers
• Coupling between antennas (equivalent to S-parameters)
• Wide range of outputs for predicted EM fields and channel characteristics
