Inductive Power Transfer Through Saltwater
J. N. Wandinger, D. M. Roberts, J. S. Bobowski +1
We investigated inductive power transfer (IPT) through a rectangular slab of saltwater. Our inductively-coupled transmitters and receivers were made from loop-gap resonators (LGRs)…
Mid-Range Wireless Power Transfer at 100 MHz using Magnetically-Coupled Loop-Gap Resonators
David M. Roberts, Aaron P. Clements, Rowan McDonald +2
We describe efficient four-coil inductive power transfer (IPT) systems that operate at 100 MHz. The magnetically-coupled transmitter and receiver were made from electrically-small…
Permittivity of waste-activated sludge by an open-ended coaxial line
J. S. Bobowski, T. Johnson, C. Eskicioglu
The complex permittivity of thickened waste activated sludge (WAS) was measured from 3 MHz to 40 GHz. The solid content of the thickened WAS sample was varied from 4.5% to 18% by w…
Permittivity measurements of biological samples by an open-ended coaxial line
J. S. Bobowski, T. Johnson
We previously reported on the complex permittivity and dc conductivity of waste-activated sludge. The measurements, spanning a frequency range of 3 MHz to 40 GHz, were made using a…
The Complex Permeability of Split-Ring Resonator Arrays Measured at Microwave Frequencies
Sabrina L. Madsen, Jake S. Bobowski
We have measured the relative permeability of split-ring resonator (SRR) arrays used in metamaterials designed to have over a narrow range of microwave frequencies. T…
