Penetration depth and conductivity of NbN and DyBa_2Cu_3O_7 thin films measured by mm-wave transmission

B. J. Feenstra, F. C. Klaassen, D. van der Marel +3

Using mm-wave transmission we obtain information about both the real and imaginary part of the dielectric function of superconducting thin films. This is done by fitting the Fabry-…
