Abstract :
The phase-shifting properties of a slow-wave microcoplanar structure are studied by means of a rigorous theoretical approach and the propagation losses are calculated. The Green function, which is used for the two-dimensional determination of the depletion layer profile, satisfies the real boundary conditions of the physical structure. The results obtained for the structure´s electrical length are compared with the corresponding experimental data and a good agreement is obtained, in particular for zero-bias conditions.
