Abstract
A THEORETICAL ANALYSIS OF THE 4-WIRE TEM GENERATOR BY LIEPA AND JAREM HAS SHOWN THAT UNIFORM TEM WAVES CAN BE GENERATED OVER A 6 FT. DIAMETER TARGET REGION AT VHF FREQUENCIES. WE HYPOTHESIZE THAT BOTH POLARIZATION AND PHASE FRONT TILT CAN BE ACHIEVED ALSO WITH THIS SYSTEM BY CONTROLLING THE FOUR EXCITATION CURRENTS INDEPENDENTLY. FOR THIS PHASE I EFFORT SIMULATION TECHNOLOGIES PROPOSES TO BUILD AND TEST A SCALE MODEL OF THE TEM GENERATOR AND TEST OUR HYPOTHESIS. THE SCALE MODEL WILL OPERATE AT S-BAND (2 GHZ - 4 GHZ) AND WILL BE USED TO ASSESS THE FEASIBILITY OF BUILDING A FULL SCALE PROTOTYPE IN PHASE II.
