abstract = "An appropriate configuration of the magnetic bias geometry used in waveguide based phase control sections can help to reduce size, bulk and energy utilization. In this paper ferrite inserts for a toroidal phase controller are fabricated using a viscous plastic processing method. This technique has been exploited to produce a low reluctance magnetic geometry that avoids machining. The magnetostatic result for the bias geometry has been computed and used to analyze the phase control characteristics of a twin toroid phase controller. The microwave response in terms of S-Parameter over 8- 12 GHz for various magnetization levels has been measured. The insertion loss of less than 1.1 dB has been achieved. The reflection coefficient (<22 dB) has been experimentally verified.",
