Abstract: The invention relates to a high-frequency transmission line including a conductive tape (6) associated with a shielding surface (4) that is placed under the line structure and is divided into parallel microstrips in a direction generally orthogonal to the direction of the line, said microstrips being movable relative to the conductive tape.

Abstract: A device formed of a sampling “plate” includes an assembly of elements for individual storage samples regularly arranged in a line x column matrix, each of the storage elements may be accessed for placing or taking a sample, a lid may be installed on the plate in order to isolate the storage elements from the environment. The lid includes movable access elements enabling, in a first opening position, to access at least one of the storage elements and, in a second closing position, to isolate the at least one of the storage elements from the environment in order to enable, in the first opening position, access to the one storage elements the lid being arranged on the plate and including one fixed part and at least one mobile part. The mobile part is a disk mobile in rotation or a plate in translation.
