Backward waves in a grounded bilayer slab containing double-negative (DNG) and double-positive (DPS) metamaterials
E. Cojocaru
Simple dispersion relations for the guided modes in a grounded DNG/DPS bilayer slab are given in terms of normalized parameters. Relations corresponding to the grounded single-laye…

Third-order triangular finite elements for waveguiding problems
E. Cojocaru
Explicit relations of matrices for two-dimensional finite element method with third-order triangular elements are given. They are more simple than relations presented in other work…
