Optimization Techniques for Permittivity and Permeability Determination
This paper discusses optimization techniques for the determination of complex permittivity and permeability in transmission lines. The traditional theoretical model using scattering parameters is extended into a mathematical regression model that can be solved with widely accepted numerical techniques. This new model produces accurate primary mode results for the samples tested including nonmag...
متن کاملDetermination of effective permittivity and permeability of metamaterials from reflection and transmission coefficients
We analyze the reflection and transmission coefficients calculated from transfer matrix simulations on finite lengths of electromagnetic metamaterials, to determine the effective permittivity ~«! and permeability ~m!. We perform this analysis on structures composed of periodic arrangements of wires, split ring resonators ~SRRs!, and both wires and SRRs. We find the recovered frequency-dependent...
متن کاملDetermination of Complex Permittivity and Permeability of Ferrimagnetic Nanopowders at Microwaves
A technique of determination of complex permittivity and permeability of ferrimagnetic nanopowders using S-parameter measurements in rectangular waveguide and results of its study are presented in this paper. The permittivity and permeability of the ferrimagnetic nanopowders are determined by the novel technique in which magnitudes of S-parameters are used only. Use of the technique allows to s...
متن کاملObstacle-based self-calibration techniques for the determination of the permittivity of liquids
In this contribution, different obstacle-based selfcalibration techniques for the measurement of the dielectric properties of liquids are investigated at microwave frequencies. The liquid under test is contained inside a waveguide, which is connected to the ports of a vector network analyzer. The permittivity of the liquid is characterized on the basis of the measured scattering parameters. In ...
متن کاملAn Electromagnetic Trinity from “negative Permittivity” and “negative Permeability”
An electromagnetic trinity comprising vacuum, anti–vacuum, and ni-hility is postulated — after making use of materials with " negative per-mittivity " and " negative permeability " — to illuminate the structure of electromagnetic theory, at least insofar as the relationship of phase velocity with Poynting vector is concerned.
