Eigenvalue analysis of planar or curved shielded or open printed transmission lines loaded with full tensor anisotropic materials

An eigenvalue analysis of curved shielded or open waveguides and planar transmission lines loaded with full tensor anisotropic materials is presented. This analysis is based on our previously established two-dimensional Finite Difference Frequency Domain eigenvalue method formulated in orthogonal curvilinear coordinates. This method is used herein in order to accurately handle closed or open curved geometries filled or partially loaded with full tensor anisotropic materials. Numerous investigations are carried out involving all type of propagating modes.
