Abstract
A variable waveguide system (). The variable waveguide system () includes a waveguide (), a dielectric structure () including at least one cavity disposed within the waveguide, and a conductive fluid (). The cavity is filled with the conductive fluid () in a first operational state, and the cavity is purged of the conductive fluid () in a second operational state. A fluid control system () can be provided for transferring the conductive fluid () in and out of the cavity in response to a control signal (). The waveguide () can have a first cutoff frequency in the first operational state and a second cutoff frequency in the second operational state. Further, the waveguide () can have a first electrical length in the first operational state and a second electrical length in the second operational state.
