We have measured the penetration depth on thin films from transmission at 120, 330 and 510 GHz, between 5 and 50 K. Our data yield simultaneously the absolute value and the temperature dependence of . In high-quality films exhibits the same linear temperature dependence as single crystals, showing its intrinsic nature, and Å. In a lower quality one, the more usual T2-dependence is found, and Å. This suggests that the T2 variations is of extrinsic origin. Our results put the wave–like interpretation in a much better position.
