Material testing: permittivity and permeability

EXONX offers services for measuring the electromagnetic parameters of materials.
It is known that permeability and permittivity change as a function of frequency. For example, a plastic such as teflon maintains its properties up to a few GHz, but then changes. With the increase in frequencies used in devices RF, it is becoming increasingly important to know the permeability and permittivity values of the materials used. High-frequency insulation materials are not transparent, and therefore spark transparency issues can occur that can significantly affect device performance. There are also many new materials manufactured using nanotechnologies that require proper knowledge of permittivity and permeability values.
The services offered are briefly summarized in the attached presentation.
