Transmission measurements in the range 130GHz--500GHz on YBa{sub 2}Cu{sub 3}O{sub 7{minus}{delta}} epitaxial thin films are reported and discussed. The authors deduce the absolute value of the electromagnetic penetration depth {lambda}(T) from the frequency variation of the transmission. They concentrate on the highest quality film, which yields {lambda}(0K) = (1,570 {+-} 200 {angstrom}), associated with a linear temperature dependence of {lambda}(t) which maps at low temperature (T < 20K) the data on high quality single crystals. They derive the real part of the conductivity from the small difference between the film and the single crystal data.
