“…The simulation results obtained for the negative index balanced structure can be verified with the help of scattering parameter measurement using a vector network analyser (VNA). Most of the scattering measurement techniques required a sample holder [42,43] and the special requirement of the sample holder can be avoided with the use of rectangular waveguide measurement. The dimensions of the waveguide will depend on the frequency range, in which parameters are to be retrieved for unknown materials.…”

Metamaterials are the artificial materials that may have a negative refractive index and results in extraordinary properties which are not found in nature. This research focusses on designing a compact-sized artificial material for negative characteristics of permittivity, permeability and refractive index over the wide range of frequencies. The metamaterial design is evaluated for single negative, double negative and double positive behaviours over a broad range of frequencies to investigate the gap and gapless transitions from backward to forward wave propagation. The dispersion diagram of the material is also investigated for left or right hand behaviour of the material. The equivalent circuit diagrams along with circuit simulations of the parameters are also presented for detailed analysis and understanding. The designed metamaterial behaves like a double negative material for low frequencies and double positive material for high frequencies. The approach is verified using CST microwave studio simulation and the results obtained are validated using the rectangular waveguide measurement method.

“…There are three kinds of conventional methods to measure the complex permeability which mainly focus on high frequency. The first is the ''transmission method'' [13]- [17], by means of the variation of the reflected and transmitted field. The measurement sensitivity drops rapidly with the decrease of the frequency due to the decreased transmission and reflection field energy at a lower frequency.…”

The ferrite magnetic shield can provide a low-noise magnetic environment for various ultrahigh-sensitivity measurements. The low-frequency complex permeability, which determines the magnetic hysteresis noise and the shielding factor, is a key parameter of the ferrite shield and thus should be measured accurately. In this paper, the measurement error of conventional coil method is analyzed at low frequency, and an improved method is proposed which could eliminate the measurement error introduced by the wire resistance. Using this method, four ferrite samples made of PC40 and PC47 materials are measured. The measurement accuracy of the low-frequency complex permeability has improved by two orders of magnitude. On the basis of the measurement results, magnetic hysteresis noise and the shielding factor of ferrite shields are calculated. The calculated results of the noise analysis indicate that the PC40 material has lower magnetic hysteresis noise. This study can help select the ferrite materials and estimate the performance for low-noise magnetic shield design.

“…In fact, this kind of problem has received very recent attention for different types of materials and with different types of probes for the input/output [15][16][17]. In this paper, two different models based on mode-matching along the longitudinal direction are proposed for characterizing the two-port problem associated with the coaxial probe for dielectric measurement of homogeneous samples.…”

The characterization of the dielectric properties of a material requires a measurement technique and its associated analysis method. In this work, the configuration involving two coaxial probes with a material for dielectric measurement between them is analyzed with a mode-matching approach. To that effect, two models with different complexity and particularities are proposed. It will be shown how convergence is sped up for accurate results by using a proper choice of higher-order modes along with a combination of perfect electric wall and perfect magnetic wall boundary conditions. It will also be shown how the frequency response is affected by the flange mounting size, which can be, rigorously and efficiently, taken into account with the same type of approach. This numerical study is validated through a wide range of simulations with reference values from another method, showing how the proposed approaches can be used for the broadband characterization of this well-known, but with a recent renewed interest from the research community, dielectric measurement setup.
