The Conformal Correction in the Strip Centered Coaxial Line Analysis
MetadataПоказати повний опис матеріалу
The presented work reports on the novel analysis of the strip-centered coaxial line. The conformal mapping method is used. For a narrow central strip a very easy conformal mapping is described that maps this structure onto the rectangular model line, but great distortion for wide strip inhibits application of this mapping in all the extent. The conformal mapping method allows to correct this fault very smartly by extension in auxiliary plane. Two different numerical models are also mentioned as comparative solutions of strip-centered coaxial line analysis. One of them is based on numerical evaluating of the Schwarz Christoffel integral, the other (in two modifications) is based on boundary element method (BEM).
