Wave motion in infinite inhomogeneous waveguides [Elektronski vir]Špacapan, Igor, 1946- ; Premrov, Miroslav, 1967-The analysis of wave motion in infinite homogeneous waveguides, having a crossection that is not simple, and/or having an irregular inclusion, is by the majority of the available methods a rather ... difficult task, especially whenstriving for exact results. On the contrary, the presented proceedure , which is in the frequency domain, is simple to apply. It yield exact results and a clear paramteric insight into wave motion. Radiation conditions are satisfied exactly. The procedure uses FE modelling of the interesting section of the waveguide, and the decomposition of the wave motion into the distinct wavemodes with constant velocities by eigenvalue problem solution. The presented examples demonstrate the effectiveness of the procedure, while the analytical results confirm its accuracy.Type of material - conference contributionPublish date - 2001Language - englishCOBISS.SI-ID - 6526742
