ABSTRACT:
A continuously variable waveguide filter (100). The variable waveguide filter can include at least one waveguide filter cavity (154, 156, 158) and a fluid dielectric (108) having a permittivity and a permeability at least partially disposed within the waveguide filter cavity (154, 156, 158). At least one composition processor (101) is included and adapted for dynamically changing a composition of the fluid dielectric (108) to vary at least one electrical characteristic. A controller (136) is provided for controlling the composition processor (101) in response to a waveguide filter control signal (137).
