Material Measurements Using VNA-Based Material Characterization Kits Subject to Thru-Reflect-Line Calibration

Ferrite material Characterization Using S-Parameters Data

ince many applications rely on the knowledge of the electromagnetic material properties of ferrites, such as ferrite phase shifters, this paper presents an algorithm for characterizing ferrite materials in a single frequency using a rectangular waveguide system. In this method, the extraction of ferrite parameters is implemented through minimizing the difference between the measured data and th...

Dynamic Characterization of Cohesive Material Based on Wave Velocity Measurements

The paper presents a description of the dynamic properties of cohesive material, namely silty clays, obtained by using one of the applied seismology methods, the bender elements technique. The authors’ aim was to present the dynamics of a porous medium, in particular an extremely important passage of seismic waves that travel through the bulk of a medium. Nowadays, the application of the bender...

Material planning for production kits under uncertainty

A kit is a specific collection of components and/or tools needed for completing a procedure or producing a product. A multiperiod material planning system for production kits under the demand and procurement lead-time uncertainty is considered when component sharing among kits is plausible. Simulation experiments show that component sharing improves the system’s service measure of average kit a...

Material identificiation using dual energy radiographic measurements

Dual Energy techniques allow an estimation of the effective atomic number and electron density through identification of the photoelectric and compton scattering components in the attenuation coefficient. However in the context of material identification, it is substantially more usefull to try and identify the material type and the thickness of the sample under investigation. Several simulatio...
