    Abstract: The present invention proposes a system of at least three concave mirrors (M1,M2,M3...) of cylindrical form, arranged with the concave part of the first mirror (M1) facing towards the second mirror (M2), with the planes defined by the straight sections of the two mirrors (M1,M2) perpendicular to each other and further arranged with the concave part of the third mirror (M3) facing towards the second mirror (M2), with the planes defined by the straight sections of the two mirrors (M3,M2) perpendicular to each other, and so forth (in other words, the successive mirrors are placed in a "crosswise" fashion with respect to their nearest neighbors). The system according to the invention is advantageous for applications in the guiding of millimeter and submillimeter electromagnetic waves for plasma physics.
