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…
Animations obtained by the finite-difference time-domain method showing the backward wave propagation in double-negative single-layer waveguides
E. Cojocaru
The materials having negative permittivity and negative permeability, which are labeled as double-negative (DNG) materials, have attracted much attention because of their unusual p…
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…
Parabolic cylinder functions implemented in Matlab
E. Cojocaru
Routines for computation of Weber's parabolic cylinder functions and their derivatives are implemented in Matlab for both moderate and great values of the argument. Standard, real…
Mathieu functions approach to bidimensional scattering by dielectric elliptical cylinders
E. Cojocaru
Two-dimensional scattering by homogeneous and layered dielectric elliptical cylinders is analyzed following an analytical approach using Mathieu functions. Closed-form relations fo…
Elliptic Cylindrical Invisibility Cloak, a Semianalytical Approach Using Mathieu Functions
E. Cojocaru
An elliptic cylindrical wave expansion method by using Mathieu functions is developed to obtain the scattering field for a two-dimensional elliptic cylindrical invisibility cloak.…
