  • Patent number: 10033080
    Abstract: A disclosed electrical cell enables experimental measurements of dielectric properties of an electrochromic material in the radio-frequency range of the electromagnetic spectrum. In an example embodiment, the electrical cell includes a layer of the electrochromic material under test that is sandwiched between a conducting base plane and a microstrip line.
