The wide use of waveguides in defense, aerospace, marine, and communications industries has driven the technology to continuously evolve. There is a driving need for more accurate and compact waveguide components at higher frequencies, while maintaining cost-effective solutions. FEKO software is an efficient and accurate solution for analyzing and designing waveguide components. It enables the creation of waveguide structures by either building a fully parametric model, or by using CAD import filters.
