Perform Fast Optimization Of Tapered WG Transformers
Waveguide tapers are often necessary when making a transition between two different types of waveguide transmission lines, such as singleridge waveguide and double-ridge waveguide. While three-dimensional electromagnetic (EM) analysis programs can help achieve good performance for such waveguide tapers, they also depend on a fairly close starting point in terms of the geometric dimensions for the transition. Fortunately, the author has developed a...

Analyze Circulator Design Equations
Circulators are essential elements in high-power microwave systems and antenna networks in which energy must be directed and isolated. Circulator design involves the use of well-studied models based on classic equations presented by Bosma.1 Although computers gain in processing speed, and computer-aided-engineering (CAE) programs grow in sophistication, these two equations nonetheless provide the background for high-frequency circulator development and modeling. Using these two...
