High Power, Magnet-free, Waveguide Based Circulator Using Angular-Momentum Biasing of a Resonant Ring
Neilson, Jeff.
In this report, we have evaluated a new class of circulator which appeared to have potential for operation at power levels greatly exceeding current technology. The circulator employs a new concept to generate non-reciprocal behavior without the use of ferrite materials. The novel circulator approach is based on parametric modulation of three, identical, coupled resonators generating non-reciprocal behavior as proposed by Estep. The resonant frequencies of three symmetrically coupled cavities ar... Show Full Abstract
In this report, we have evaluated a new class of circulator which appeared to have potential for operation at power levels greatly exceeding current technology. The circulator employs a new concept to generate non-reciprocal behavior without the use of ferrite materials. The novel circulator approach is based on parametric modulation of three, identical, coupled resonators generating non-reciprocal behavior as proposed by Estep. The resonant frequencies of three symmetrically coupled cavities are modulated by an external RF driver at the same amplitude and a relative phase difference of 120 degrees. This cavity modulation imparts an effective electronic angular momentum to the system and generates the non-reciprocal behavior of a circulator Show Partial Abstract
