The Wilkinson Microwave Anisotropy Probe
The Wilkinson Microwave Anisotropy Probe (WMAP) has mapped the full sky in five frequency bands between 23 and 94 GHz. The primary goal of the mission is to produce high-fidelity, all-sky, polarization-sensitive maps that can be used to study the cosmic microwave background. Systematic errors in the maps are constrained to new levels: using all-sky data, aspects of the anisotropy may confidentl...
متن کاملThe Microwave Anisotropy Probe (MAP) Mission
The purpose of the MAP mission is to determine the geometry, content, and evolution of the universe via a 13 arc-min full-width-half-max (FWHM) resolution full sky map of the temperature anisotropy of the cosmic microwave background radiation with uncorrelated pixel noise, minimal systematic errors, multifrequency observations, and accurate calibration. These attributes were key factors in the ...

متن کاملReducing an Energy Reflection from Applicator for Microwave Wood Treatments
The microwave processing of wood is a widely used as high intensity microwave treatment creates changes in wood structure, which might significantly contribute to the development needs of timber industry, by accelerating wood drying time, relieving of growth stresses, facilitating preservative impregnation and enabling the production of solid wood products. Microwave wood modification requires ...
متن کاملStability and Gain Prediction of Microwave Tunnel-Diode Reflection Amplifiers
The Nyquist approach to stability is used in a form suitable for representation on a chart having conventional Smith chart scales. It is shown how the gain and stability of negative conductance reflection amplifiers of the tunnel-diode type can be simultaneously predicted on this chart. The technique described is particularly useful in the practical design of these amplifiers embedded in networ...
