            Abstract : 
The use of liquid suspensions as a new class of microwave artificial dielectrics was explored. Liquid media were constructed with permittivities dependent on the strength of a low-frequency electric control field. Operating characteristics were measured for a 50 KW, 360/spl deg/ Ku-band waveguide phase shifter employing a practical liquid-suspension dielectric. Other applications are in electrically variable wideband lenses and in the analog control of phased arrays.
