Gaussian Beam Analysis

Model and analyze parabolic reflector antennas using Gaussian-beam method

The Gaussian‑beam method for reflector 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. This approach is particularly valuable at millimeter‑wave and sub‑millimeter frequencies, where reflector apertures 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.

Use the object and functions in this category to perform Gaussian-beam-based design and evaluation of parabolic reflector antennas commonly used in satellite, airborne, and terrestrial high-gain communication and radar systems.
