Abstract
A system of at least three concave mirrors (M1, M2, M3 . . . ) of cylindrical form are arranged with the concave part of the first mirror M1 facing towards the second mirror M2 and with the planes defined by the straight sections of the two mirrors which are perpendicular to each other. The arrangement further has 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 perpendicularly to each other. Successive mirrors are placed in a crosswise fashion with respect to their nearest neighbor in order to provide for applications in the guiding of millimeter and sub-millimeter electromagnetic waves for plasma physics.
