Abstract
A vacuum-tight window arrangement includes a hollow cylindrical housing having an aperture in each end which constricts the width of a waveguide between the apertures. The waveguide carries a transversely mounted dielectric window. A combination of proportioning rules based on waveguide width, aperture width, aperture thickness, window-to-aperture distance and wavelength of the center frequency provide a window arrangement which is stable with respect to interfering modes over a large frequency range at high operating efficiency and very short wavelengths.
