A new H10-to-H20 mode transducer
Proceedings of the IEE Part B: Electronic and Communication Engineering, 1960Using a general method of mode-transducer design previously described, a simple H10-to-H20 mode transducer was constructed. The reflection coefficient is calculated, and it is shown that for a transducer a few wavelengths in length the reflections are insignificant. The power transferred to the spurious modes was measured by the resonance method on two

Low-Luminosity Extra-Galactic H20 Masers
2005Recent high-resolution observations of low-luminosity extra-galactic H2O masers towards M 82, M 51, and NGC 4051 are presented in this contribution. These observations were conducted using the very large array (VLA). The general observational properties of these masers are discussed.

Here to Observe (H20) and Europa Clipper
Introduction: The Here to Observe (H2O) program was established in 2021 to pair mission teams with institutions with large populations of underrepresented and historically marginalized students, to provide an opportunity for participants in the program an insider’s view of how NASA missions operate, as well as one-on-one mentorship of the ...Rachel L.
