Gaussian Beam Analysis
R2026bThe Gaussian‑beam method for antenna modeling and analysis is a highly efficient alternative to computationally intensive numerical methods such as physical optics (PO). By representing the electromagnetic field through closed‑form expressions for beam amplitude, phase, and wavefront curvature, this method enables you to quickly and accurately evaluate field propagation through large reflector systems as well as in phased arrays. This approach is particularly valuable at millimeter‑wave and sub‑millimeter frequencies, where reflector apertures and array sizes become electrically large and conventional PO surface integrations become prohibitively slow. The Gaussian‑beam method is therefore an effective tool for fast performance prediction, beam‑shaping analysis, and early‑stage design of high‑gain reflector antennas and phased arrays.
Use the objects and functions in this category to perform Gaussian-beam-based design and evaluation of parabolic reflector antennas and phased arrays commonly used in satellite, airborne, and terrestrial high-gain communication and radar systems.
