Measurement services of the electromagnetic properties are available in the frequency range 1 MHz to 8 GHz for liquids, powders, foams; and 1 MHz to 18 GHz for all types of solid materials.
Entire range of moisture content (0% to 100% MC) can be characterized for porous or granulated materials, such as soils.
The density of a powder or soil can be characterized with a density equivalent to a pressure up to 2 ton/cm2. In many cases, the permittivity, permeability and conductivity of soils have a proportional relationship with density, being possible to extrapolate to higher unmeasurable densities.
The addition of foreign substances in a solution or material generally influences the electromagnetic properties. For example, specific salt concentrations can decrease the growth of pathogenic microorganisms in food; since conductivity is largely impacted by salt concentration, this is a determinant factor for food quality. We can establish a trendline to determine the concentration of a specific substance in your material or solution.
The electromagnetic properties of several material samples can be characterized as function of frequency and another parameter, to obtain a full variance spectrum.
