| 摘要 |
<p>The invention concerns a waveguide comprising a main tubular element having a tubular portion (2) with constant cross-section extended by a substantially truncated flared portion (3), the tubular portion(2) bearing several cylindrical cavities radially distributed about the axis of the main tubular element, the axis of each cylindrical cavity (4) being located in a plane perpendicular to the axis of said main tubular element. The waveguide consists of two separate parts (1A, 1B) assembled end-to-end along a plane wherein are located the axes of the cavities (4).</p> |
