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.Technology: general issuesbicsscDiffractionMode convertersOversized WaveguidesScatteringWaveguide AntennasTechnology: general issuesFlamm Jens Hanspeterauth1842991BOOK9911115608303321Diffraction and Scattering in Launchers of Quasi-Optical Mode Converters for Gyrotrons4423661UNINA
