Abstract :
An original structure, an active coupled coplanar waveguide on GaAs substrate, is proposed, where a quasi-TEM analysis using Green´s functions leads to the determination of the slow-wave characteristics in this structure. It is shown that the nonreciprocal characteristics can be controlled through the DC-biasing of the different device elements.
