Time domain measurement of complex-permittivity and complex permeability of materials

14th International Conference on Microwaves, Radar and Wireless Communications. MIKON - 2002. Conference Proceedings (IEEE Cat.No.02EX562), 2003
Time domain measurement of complex permittivity and complex permeability is considered. Two methods are presented for measuring. measuring in the 2 to 18 GHz frequency band using a horn antenna and measuring in a coaxial waveguide. Some modifications of measurement scheme for the determination of permittivity and permeability are presented and ...

Synthesis and complex permeability of Ni/SiO₂ nanocomposite

Nanotechnology, 2004
The magnetic properties of Ni/SiO2 nanocomposite prepared by a simple sol–gel combined hydrogen reduction method are reported. The real part of the permeability for Ni/SiO2 nanoparticles is almost independent of frequency up to at least 1 GHz, and the loss of is very small.

Permeability characteristic of polyelectrolyte complex capsule membranes: Effect of preparation condition on permeability

Journal of Applied Polymer Science, 1996
Because polyelectrolyte complex formation is known to depend on charge densities of polyelectrolytes, influence of pH condition in the preparation of the polyelectrolyte complex capsules on their permeability characteristic for phenylethylene glycol was examined.

Complex redundancy to build a simple epidermal permeability barrier

Current Opinion in Cell Biology, 2003
To survive the transition from an aqueous in utero to a terrestrial ex utero environment, mice and humans must construct an epidermal permeability barrier in utero. Terminally differentiated epidermal cells, lipids and tight junctions are all essential to achieve this barrier.

Water Permeability Measurement in Living Cells and Complex Tissues

Journal of Membrane Biology, 2000
The identification of molecular water transporters and the generation of transgenic mice lacking water transporting proteins has created a need for accurate methods to measure water permeability. This review is focused on methodology to characterize water permeability in living cells and complex multicellular tissues.
