Abstract
A continuously variable waveguide attenuator (). The continuously variable waveguide attenuator includes at least one waveguide attenuator cavity () having at least one barrier. A fluid dielectric () having a loss tangent, a permittivity and a permeability is at least partially disposed within the waveguide attenuator cavity (). At least one composition processor () is included and adapted for dynamically changing a composition of the fluid dielectric () to vary an electrical characteristic of the fluid dielectric. A controller () is provided for controlling the composition processor () to selectively vary the electrical characteristic in response to a waveguide attenuator control signal ().
