Waveguide for transmitting microwave signals

The invention relates to a waveguide in the form of a waveguide for transmitting microwave signals, characterized in that at least one electrically non-conductive body arranged in and/or on the waveguide and at least one MHD pump are provided, by means of which an electrically conductive liquid medium can be loaded, and at least one filling means for filling the at least one body and/or for applying a force to at least one wall of the waveguide body. 本发明涉及一种呈波导管形式的用于传输微波信号的波导体，其特征在于，设有布置在所述波导体中和/或所述波导体上的非导电的至少一个体和设有至少一个MHD泵，通过所述MHD泵能够加载导电液态介质，用于充注所述至少一个体和/或用于将力施加到所述波导体的至少一个壁上。
