The permittivity of a barium strontium titanate thin film was measured at 1.8 GHz and 4.4 GHz with a scanning evanescent microwave microscope (SEMM) and co-planer waveguides (CPW). The raw data suggests the SEMM has sufficient sensitivity to detect significant variations in permittivity across the film that the CPWs could not. The average value of permittivity extracted from the data is consistent...
The Soil Moisture Experiments in 2004 and 2005 were conducted to validate algorithms for soil moisture retrievals. One of the key parameters for determination of soil moisture from microwave sensors is the vegetation water content of canopy and stems. We tested if canopy water content could be determined from reflectances in the shortwave-infrared and if the amount of canopy water content was related...
