Abstract :
The inhomogeneous dielectric loading approximation applied in analysis method for helix slow wave structure has been improved for higher accuracy. The compensation of rod dielectric constant approximation by a formula considering the helix dimensions has been proposed. Comparisons with 3D simulator results confirm the effectiveness of the proposed approach.
