Application of a hybrid domain decomposition approach for the analysis of large reflector antennas

An approach for the analysis of large or very large reflector antennas is presented in this work. This technique provides accurate results (similar to those obtained by using pure full-wave methods), while lowering the CPU-time and the memory resources required to perform the simulations. The geometry is divided into different domains. The basis functions within each domain are considered fully coupled, and the interactions between different domains are computed iteratively.
