In recent years, we have become familiar with using commercial software to design our antennas and microwave devices. This is very common because high-performance desktop computers are easy to find at affordable prices in our daily lives. The use of general-purpose commercial software is widespread because it enables the simulation of arbitrary configurations. However, many of us have experienced, given the ease of using commercial software, the difficulty of simulating electrically large electromagnetic devices, which can take days or, in some cases, cannot be completed at all. While it is true that we now have very powerful simulation tools, by making a few simple assumptions, we can significantly reduce computational time without sacrificing accuracy . In this talk, I will introduce a simple ray-tracing technique that can be used, in combination with physical optics, to calculate the radiation pattern, directivity, gain, mutual coupling, and even the early-time response of antennas in complex configurations . The results are not only faster than those produced by conventional commercial software, but also more accurate, as they avoid many of the numerical errors that typically arise when computing electrically large structures.
