Abstract
A waveguide in the form of a wave duct for transmitting microwave signals includes at least one non-conducting body arranged in and/or on the wave duct, and by at least one MHD pump, by which an electrically conductive liquid medium can be admitted to fill the at least one body and/or to exert a force on at least one wall of the wave duct.
Claims19
A waveguide arrangement for microwave signals, the waveguide arrangement comprising:
- a waveguide structured with one or more wave passages for transmission of the microwave signals over the one or more wave passages;
- at least one non-conducting body over which the microwave signals are not transmitted and that is arranged near the one or more passages of the waveguide;
- and
- at least one magnetohydrodynamic (MHD) pump, by which a fill of the at least one non-conducting body with an electrically conductive liquid medium is dynamically modifiable to thereby control a change in at least one of an attenuation, a phase, and a reflection of the microwave signals that are in the one or more passages of the waveguide.

A waveguide arrangement for transmitting microwave signals, the waveguide arrangement comprising:
- a wave duct;
- at least one non-conducting body arranged on at least one wall of the wave duct;
- and
- at least one MHD pump by which an electrically conductive liquid medium can be admitted to fill the at least one non-conducting body and/or to exert a force on at least one wall of the wave duct;
- wherein at least one slot in the wave duct can be closed and opened by the at least one non-conducting body to influence a coupling state of the wave duct.
