Copper Mountain along with Compass Technology has released a new Epsilometer solution for measuring the dielectric properties of materials. It measures dielectric substrate materials at frequencies from 3 MHz up to 6 GHz and can accommodate sheet specimens 0.3 to 3 mm thick.
Unlike previous dielectric analysis technologies, the new method uses computational electromagnetic modeling to invert the dielectric permittivity and loss. This represents a significant advance over conventional methods, which use analytical approximations and are limited to frequencies below 1 GHz.
With the launch of Epsilometer, Copper Mountain delivers another solution that combines its metrology-grade portable network analyzers with subject matter expertise to solve important industry problems. Accurate determination of dielectric properties of radomes, packaging, and microwave substrates is important for design of functioning wireless devices for the Internet of Things and emerging 5G applications.
This innovative Epsilometer is based on Copper Mountain's R60 1-Port Vector Network Analyzer.
