Web7 Jul 2024 · The greater the dimension of the wave guide in \(\lambda \), the greater is the directivity of this power pattern. However, the larger the cross-section of a wave guide in terms of the wavelength, the more difficult it becomes to restrict the wave to a single mode. Thus wave guides of a given size can be used only for a limited frequency range. Submillimeter Wave Astronomy Satellite (SWAS, also Explorer 74 and SMEX-3) is a NASA submillimetre astronomy satellite, and is the fourth spacecraft in the Small Explorer program (SMEX).
