Microwave Characterization Of Electro-Optic Polymers

Abstract: Electro-optic polymer thin-films were characterized at microwave frequencies, for possible applications in GHz modulators. Single layers of the polymers were spin coated on low loss magnesium oxide substrates for characterizing the polymers at microwave frequencies. Coplanar waveguide test structures were designed for evaluation of the relative dielectric permittivity as well as the loss-tangent of the polymers at microwave frequencies. A conformal mapping technique was used for the extraction of relative diel… Show more

“…Loss in PMMA samples was very low, and ε ′ ′ was not measured. This matches the reference and published data for PMMA in the microwave frequency range: = ′ ε 2.2-2.8, and = ′ ′ ε 0.01-0.3 [16][17][18][19].…”

“…This value differs from 16% with the value of 3.01 found in litterature. 7 This result should be take carefully, as it is our first measurement using this method. We are currently working on the result accuracy improvement, by lowering the frequency measurement error.…”
