The extension gives the opportunity to take a tapered average radius of the waveguide antenna into account. The comparison and the extension of the fast field calculation methods for component synthesis opens the possibility to reduce diffraction and stray radiation of reliable and powerful millimeter wave sources.EnglishTechnology: general issuesbicsscDiffractionMode convertersOversized WaveguidesScatteringWaveguide AntennasFlamm, Jens Hanspeteraut3-86644-822-8DOAB Library.BOOK991004233124907536Diffraction and Scattering in Launchers of Quasi-Optical Mode Converters for Gyrotrons4423661UNISALENTO
