    An effective-medium model for high-impedance surfaces

    We show that high-impedance surfaces with complex microstructures can be well described by a double-layer effective-medium model consisting of an anisotropic meta-material layer (with a dispersive permeability...

    ISO2002: an analytical stochastic model of multi-difference GPS carrier-phase data

    The differencing technique is useful in global positioning system (GPS) positioning when two or more GPS receivers collect simultaneous observables from common satellites at each epoch, and all carrier-phase o...

    Investigation of ytterbium fulleride compounds

    We have synthesized the ytterbium fulleride compounds YbxC60 (x=1–6) at a range of lower temperature (530 °C–570 °C). Except for the nominal composition Yb3C60 compound, which has been reported in the references,...
