Abstract
Abstract : An investigation was made of a shielded twin inner conductor transmission line as the vehicle for obtaining extremely broad bandwidth nonreciprocal coaxial components. The inner conductors were coupled through a coextensiv magnetized ferrite rod and a proc s completely analogous to Faraday rotation transferred nergy between the conductors. The rotational process was essentially flat for frequencies of twice the magnetization and higher. The TEM transmission structure offered no dispersion but limited the highest frequencies. The principles of gyromagnetic coupling are an lyzed and a formullation determined which covers the simultaneous eff cts of reciprocal and o reciprocal coupling. M an are di cu e to eliminate reciprocal coupling as well as backward wave coupling. Experimental results confirmed the large bandwidth produced with nonreciprocal coupling where flat coupling was observed between 1.8 and 5.6 kmc.
